Package: nagios-common Version: 2:1.3-cvs.20050402-2.sarge.2 Severity: normal
On occasion, the /etc/init.d/nagios script, when told to restart Nagios, does not stop the old Nagios process before starting another one. This leaves two Nagios processes running. This may be related to #294178, although the fix described therein seems to be present in the version I have installed.

The newer process, 6791, wouldn't respond to anything but kill -9. The problem's a bit difficult to reproduce, but it's happened frequently enough in the past that I've taken to stopping Nagios, checking that all 'nagios' processes are dead, and only then starting it, instead of using '/etc/init.d/nagios restart'.
