Public bug reported: Binary package hint: nagios2
The init script for nagios kills nagios when the user requests the configuration to be reloaded. Nagios logs that it has received a SIGTERM rather than the expected SIGHUP. This appears to be a bug in the nagios2 (2.11-1ubuntu1) packages interaction with the lsb-base package in Hardy. This bug is not present in Debian with the 2.11-1 version of the nagios package. The nagios init script calls killproc from the lsb-base scripts, passing it "1" (HUP) as the signal to send to nagios, the lsb-base scripts convert this to a TERM instead of a HUP. I do not know if this is a bug in the lsb-base scripts, or the scripts being called incorrectly by the nagios init script, so I have filed this bug on Nagios as I suspect it is the more likely candidate to be at fault, it will be amazing if such a large bug in lsb-release managed to slip through the QA for an LTS release! To reproduce the bug on a Hardy system you can do the following: 1) Install nagios2 2) Start nagios, check that it is running, tail /var/log/nagios2/nagios.log 3) In another console run, /etc/init.d/nagios2 reload 4) Observe the following lines in the log file [1212255142] Nagios 2.11 starting... (PID=24439) [1212255142] LOG VERSION: 2.0 [1212255142] Finished daemonizing... (New PID=24440) < reload command is executed at this point> [1212256400] Caught SIGTERM, shutting down... [1212256401] Successfully shutdown... (PID=24440) I have attached a patch that works around this issue by modifying the init script to send a HUP directly rather than using the killproc method from the lsb-base scripts. When this patch is applied the correct behaviour is observed in the nagios log file after executing /etc/init.d/nagios2 reload [1212256426] Nagios 2.11 starting...
