And what does this mean? Is it as bad as I felt it was. I had to restart Zope. Yes it is bad!

File C:\Program Files\Zopesite\lib\python\Products\FSSession\FSSession.py, line 206, in final_commit (Object: gmisSession) OSError: [Errno 2] No such file or directory: 'C:\\Program Files\\Zopesite\\var\\FSSession\\052\\10\\12\\0521 0120924410130' I have seen this behaviour with very old versions of "FSSession", when the same session object was accessed by different threads (e.g. from a frame) at the same time. Newer "FSSession" versions should no longer exhibit this problem.
