Comment 8 for bug 122001

I am seeing this issue too. I do not use gannotate or viz or any GTK. I am just checking out a straight, exclusive Python branch. I have seen this once before and found no way to cure it! It is extremely vexing because once this occurs, it is permanent and a whole new fresh checkout of the 1/3 gb of data in the Python repository must be downloaded fresh and one must start again! This takes an EXTREMELY long time. And this seems to effect every bzr operation from switching to merging.

Here is my error report:

bzr: ERROR: bzrlib.errors.LockContention: Could not acquire lock "[Errno 11] Resource temporarily unavailable"

And when I try to break locks:

bzr: ERROR: bzrlib.errors.LockActive: The lock for '/home/crew/user/Regexp-2.6' is in use and cannot be broken.
