Good morning,

I ran into this problem recently, too.

First: So far I can tell that there might be some circumstances where the
working copy is left locked on svn update/status/add/remove operations even
though there was no error that caused a crash of svn. Thus all locks *should
be* released once svn terminates.

Second: I can confirm that it is not a problem with tortoisesvn since this
happened to me while using a self-written svn frontend that interacts with
svn on the commandline.

Since it did not happen very frequently to me I did not try to reproduce the
error and - to be honest - I don't bother because it happened only once or

But there is indeed some noise in the subversion-users mailing list
regarding this problem. I'm going to quote one:

Could something like this be your problem? Meaning: are you accessing your
working copy concurrently from different threads/processes? There might be
some interesting race conditions treasured in 1.7.X that haven't been found
yet, as Markus Schaber already mentioned on 14.02.2012 12:57:
