There is a small timeframe between checkproc'ing for logrotate and starting it, and if Murphy calls in, you might end up with two instances of logrotate running. Please implement some better locking to avoid this race condition. (The article discusses some methods, but I'm not sure if it's available in english.) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
