I have checked yesterday and i was able to sync my existing svn version. I’m using RapidSVN, but i’m also able to browse svn with the Fisheye. What tool are you using?
I’ve got the same error with Tortoise SVN when doing a fresh Checkout and also it freezed at some point. Every time i just did the SVN Update afterwards and it keeps updating. Probably this is somehow related how igniterealtime server is configured. It doesn’t support download resume and maybe has some other limitations, e.g. nightly builds dowloads often break so you have to redownload it again. I have already complained about this in the forums, but that’s the only thing we can do. Jive Software runs this server (for free).
UPD: after 3 SVN Updates it has eventually completed the checkout, i think.
When it shows you that error, close Tortoise window, right click the folder with the source and choose SVN Update. Repeat this if you get another error or if it gets stuck. Until you see “Completed”. To check if it has downloaded the whole source you will have to compile this thing
