title: Subclipse on a Mac in a Windows network. Can't Commit - Can't get exclusive lock
body: <p>I have an iMac running OS X 10.7.3. I have Eclipse Indigo and Subclipse 1.8.6 installed. I'm able to connect to and save files to our repository through Finder when I provide proper credentials. I am able even to check out projects. When I make changes to the checked out project, I see the update icon, I can even view conflicts in diff.</p>
  
  <p>The problem occurs when I try to commit code, I am unable to get an exclusive lock, and the commit fails. </p>
  
  <pre><code>org.apache.subversion.javahl.ClientException: svn: E204899: Commit failed (details follow):
  svn: E204899: Can't get exclusive lock on file '/Volumes/TECHSUPPORT/SOFTWARE/Java_Projects/db/txn-current-lock': Operation not supported

  <p>I've tried everything I can think of, I've used both available SVN's. There doesn't seem to be much on the issue.</p>
  
  <p>Thanks. </p>
