[Mailman-Users] Could not acquire qrunner lock error

[mikeraz at patch.com]

My system ran out of disk space and thus, many of the Mailman processes failed.
After freeing up some space Mailman was not delivering mail and I found the 
qrunner logs had several error messages "Could not acquire qrunner lock"

the Mailman locks directory contained several files.  After some trial and
error I just deleted them all.  

Is it safe or advisable to do a `rm -f /home/mailman/locks/*` in a situation
like this?

What is the course of action one should take?
