I got a plain-text logfile (not lock file) in /var/log what I cannot open with:
lockfile creation failed: exceeded maximum number of lock attempts
I wonder what causes this and how can I unlock it without rebooting the server or other drastic measures.
lsof +D /var/log/backups/
Checking it with lsof nothing else is accessing this directory and the rsync process which output was redirected to this log file is terminated already.
I can open all other log files in this directory.
The stats on this file are:
