Hello!

My company wants me to upgrade the timeworn zope-2.7.4 to one of the newest ones available.
I decided to take zope-2.11.1 but after installing and running it in debug-mode i get the following error-messages:

2008-08-01T09:04:39 ERROR Zope.ZODBMountPoint Failed to mount database. ZODB.lock_file.LockError (Couldn't lock 'D:\\workspace_zope\\xla-2008/var/Stdcontainer_o.fs.lock')

These are not the only ones, I get the first one for 5/18 databases and the second one 6 times when running the /manage site
Do I have to be worried about those error messages or not?

Another thing is that those messages appear only once every restart but the functionality of the pages hostet isn't affected...

Hope you can help me,
