some process keeps the INBOX locked, but does not touch the file, so it 
looks like a stale lock.

Therefore some other process had broken the lock and had appended a 
message.

then the former process(es) finish and try to clean up, but the "some 
other process" already deleted the lock file.

So you have to check your system why a process, that as locked INBOX, is 
stalled for more than 120min.
