Pidgin randomly disconnecting from Openfire

Hello,

 

We're having a handful of users who are reporting random disconnects from our Openfire server. The common theme seems to be that they're all using pidgin. This was happening in both Openfire 3.5.2 and the newest version of Openfire 3.6.0. Here's the stack trace I see in the logs when someone gets disconnected:

Original IQ: <iq type="result" id="xxx-xxx" to="servername.xxx.com" from="user@server.xxx.com/Home"><query xmlns="http://jabber.org/protocol/disco#info"><identity category="client" type="pc" name="pidgin"/><feature var="jabber:iq:last"/><feature var="jabber:iq:oob"/><feature var="jabber:iq:time"/><feature var="xmpp:urn:time"/><feature var="jabber:iq:version"/><feature var="jabber:x:conference"/><feature var="http://jabber.org/protocol/bytestreams"/><feature var="http://jabber.org/protocol/disco#info"/><feature var="http://jabber.org/protocol/disco#items"/><feature var="http://jabber.org/protocol/muc"/><feature var="http://jabber.org/protocol/muc#user"/><feature var="http://jabber.org/protocol/si"/><feature var="http://jabber.org/protocol/si/profile/file-transfer"/><feature var="http://jabber.org/protocol/xhtml-im"/><feature var="urn:xmpp:ping"/><feature var="http://www.xmpp.org/extensions/xep-0199.html#ns"/><feature var="http://jabber.org/protocol/mood"/><feature var="http://jabber.org/protocol/mood+notify"/><feature var="http://jabber.org/protocol/nick"/><feature var="http://jabber.org/protocol/nick+notify"/><feature var="http://jabber.org/protocol/tune"/><feature var="http://jabber.org/protocol/tune+notify"/><feature var="http://www.xmpp.org/extensions/xep-0084.html#ns-metadata"/><feature var="http://www.xmpp.org/extensions/xep-0084.html#ns-data"/><feature var="http://www.xmpp.org/extensions/xep-0084.html#ns-metadata+notify"/></query></iq>

    Re: Pidgin randomly disconnecting from Openfire

    Hi,

     

    I routinely see that error with my pidgin users, but I don't believe it produces a disconnection.  Are you sure about that association?

     

    Wanna try setting xmpp.client.idle to -1 on the Server settings of the admin console and see if that helps your disconnects?

      Re: Pidgin randomly disconnecting from Openfire

      Hi Daryl,

       

      You're right. This error does not appear to be producing the disconnection. I made this change, but the disconnects are still happening. I've been working closely with a user trying to figure out the source of the disconnects. He got disconnected, I went to the logs, and saw a couple of these errors, but not for the user in question. He got dropped at 2008.08.28 16:57:41, which is the same in the logs that these errrors appeared.

       

      Again, this only happens for pidgin, and it also seems like all of the users are getting disconnected at the same time...

       

      Compression is turned off and xmpp.client.idle is -1... we do have TLS enabled... that's the only other thing I can think of?

       

      Is this an Openfire issue or something with our network? Any ideas?

        Re: Pidgin randomly disconnecting from Openfire

        Hi,

         

        The server config setting will only take effect for *new* connections.  Are you still seeing disconnects after clients newly connect after the config setting change?

         

        Otherwise, please consider starting one of your pidgin clients with the -d flag and see if you can trace what is happening.

          Hi Daryl,

           

          Your suggestions, along with the new release of Pidgin, seem to have substantially improved this issue for us. However, we're still having users report disconnects every once in a while. Sometimes there aren't any errors or warnings or anything when someone drops. Is there some kind of interoperability issue between Pidgin and Openfire?

            Hi,

             

            There are some issues that can cause trouble with Pidgin and Openfire.  In fact, you will find my name a lot in the Pidgin bug trac referencing some of these problems.  Invariably, the Pidgin devels point their finger at Openfire for causing the troubles and the openfire devels are more keen on supporting issues with spark[web].  I don't believe the pidgin devels test against openfire for various reasons, so what's my point...

             

            If you have troubles, try to open up the XML debug console on Pidgin and see if you can catch the disconnect in action.  Putting openfire into debug mode may help as well...

             

            I have an install base of 2900 users, with most of them running Pidgin, but for the most part, things work just great! If they continue to look bad for you, check out other clients, like Spark (hi winsrev ).  Thankfully, there are many quality options out there.

             

            HTH,

              daryl

            You mean, you already tried 2.5.1? Cause i saw in the changelog:

              Re: Pidgin randomly disconnecting from Openfire

              Yes, apparently this is still happening under 2.5.1. I've asked the users who are having these issues to start debugging their Pidgin sessions and send me the logs when they crash, but I've yet to receieve one

                Re: Pidgin randomly disconnecting from Openfire

                Same issue here with Pidgin, random disconnects after upgrading the version of Pidgin to 2.5.2 from 2.3.1.  The old version works fine but the new version disconnects.  It looks like the main change in Pidgin was the way it handles SSL certificates.  Any ideas?

                  Re: Pidgin randomly disconnecting from Openfire

                  Openfire: 3.6.4

                  Pidgin: 2.5.8

                   

                  I have the xmpp.idle set to -1 for my server settings as well.  When the disconnects occur it does not do all users at once, but tons of users get disconnected and eventually reconnect...sometimes dozens of times. I have TLS as well.

                   

                  Debug from Openfire while the disconnect dance was going on:

                    Hello,

                    I'm also familiar with this kind of a problem with Openfire+Pidgin. In a company I work we deployed Openfire 3.6.4 server and all of our users are connecting via Pidgin. After a while we noticed that server randomly closes connections. I've tried to change configuration of Openfire, Pigdin, also tried to manage traffic to the server but nothing helped. After some research I found this ticket on Pidgin website: http://developer.pidgin.im/ticket/10767

                    I think everything is explained in it.

                      Just out of curiosity is this Openfire server on a VM or bare metal?  Mine is on a VM...not sure if there is an underlying issue there. My issue also seems to happen regardless of iptables enabled or disabled.  With the lastest Pidgin 2.6.6 now, I can confirm this issue still happens at random.

    Pidgin 2.7.0 has corrected the issue. We are no longer seeing users disconnect/reconnect all day.

      Re: Pidgin randomly disconnecting from Openfire

      Yes, Pidgin developers finally managed to implement keepalives packets This is a bit late now, but you've could eliminate this issue by modifying idle settings. http://www.igniterealtime.org/community/docs/DOC-2053

        I tried putting the keepalives setting to -1 as mentioned in a few posts. Made no difference, Pidgin would still disconnect.

            Re: Pidgin randomly disconnecting from Openfire

            Can't really say, beacause I've already moved to ejabberd-2.1.3 server and the problem has gone - no random disconnections. I think that it's not the problem of Pidgin client but Openfire. Pidgin devs also claim that Openfire uses strange keepalive policy. OF require that keepalive packets are sent at some specific time interval no matter if ther is or isn't any packet transmission between client and serwer. On the other side Pidgin sends keepalives only when there is no traffic to/from server. Thus if e.g. one or more contacts on our list changes status often Pidgin sees that there is traffic from server so won't send keepalive packet, in result Openfire think that if no keepelive was sent session is dead and closes connection. IMO Pidgins policy is quite logical and bandwith-saving. Let's imagine Openfire with 1KK users logged at a time and sending simultainously keepalive packets... Looks like packet flooding for me

          Re: Pidgin randomly disconnecting from Openfire

          i have several users using pidgin 2.7.0, adium, and pandeon.

           

          most of my disconnects are with pandeon, but am seeing these come from all different clients.

           

          i have NOT changed the keep alive settings to -1, because i have see most of the post saying that it make any difference.

          also we do not want to have idle connections sitting around on out servers.

          i did increase the time before cutting off idle times out to 30 minutes. with no change.

           

          i am using openfire 3.6.4.

           

          i dont have any messages coming though the error.log.

           

          i have messages in warn, and info. but i cant decide if they are actually saying anything about disconnects.

          there have been many disconnects as of late, and not of the log messages seem to line up with the actual disconnects.

           

           

          i have seen many posts with this issue, but no one ever seems to find an answer
