title: SVN commit doesn't complete
body: <p>When I commit files in svn I often get the situation where after it has transmitted all the files svn will hang and then eventually time out with the error <code>svn: E175012: Connection timed out</code>.</p>
  
  <p>This seems to happen when I am uploading more than say 20 files.</p>
  
  <p>I believe this is happening after all of the files have been transferred to the server as either new periods will have stopped being added after <code>Transmitting file data</code> in the console, or all of the files have been listed as sent in Tortoise.  Also, if I then do an update from the repository I get merges for all of the files I've just tried to commit (or, more annoyingly, a ton of conflicts to resolve) and when I then go to commit again there is nothing to commit - presumably meaning all of the files were successfully transmitted the first time.</p>
  
  <p>What could be causing this?  It seems like the client is waiting for a 'all done' message from the server that is never arriving back at my PC?</p>
  
  <p>Our set up is TortoiseSVN 1.8.2 on the client and VisualSVN Server 2.7 on the server.</p>
  
  <p>I've checked for error messages in VisualSVN's event log on the server and there aren't any. This happens on both the office network and over VPN, and whether working on Wi-Fi or a wired connection.</p>
