SEGV in 2.0b2 (FreeBSD 4.10/200 hosts/330 active/300 passive) - repeatedly after 2-7 days running.

[Stanley Hopcroft]

Dear Folks,

I am writing to report what may be a problem with Nag 2.0b2 (embedded 
Perl, pthread lib, FreeBSD 4.10).

Nagios runs no more than 10 days before dieing with a SEGV.

Like a former report of SEGVs ('coredumps in wobbly 
networks'/Ericsson/24 Mar 2005) there _may_ be a pattern in the logged 
messages before the SEGV.

Exitting from scheduled downtime appears to be a health hazard.

In the last case,

Sat Apr 02 17:05:42 SERVICE DOWNTIME ALERT: 
foo:bar via the blurfl provider 
infrastructure;STOPPED; Service has exited from a period of scheduled 
downtime
Sat Apr 02 17:06:18 Auto-save of retention data completed successfully.

Sat Apr 02 18:07:33 Nagios 2.0b2 starting... (PID=97771)

tsitc> grep nagios /var/log/messages
Apr  2 17:07:52 tsitc /kernel: pid 3400 (nagios), uid 1000: exited on 
signal 11

And the one before,

Tue Mar 29 06:20:58 SERVICE ALERT: nada;TEC CPU;WARNING;HARD;1;The 
percentage of CPU in idle state is low. This indicates high CPU 
overload. date: 03/29/2005 06:20:50 AM eventid: 1112041070

ITM.OS.Unix_Dev_Monitoring.itm#IPAustralia-region source: TMNT status: 
OPEN

Tue Mar 29 06:30:44 SERVICE DOWNTIME ALERT: yada;Standard host-centric 
checks;STOPPED; Service has exited from a period of scheduled downtime

Tue Mar 29 06:30:44 SERVICE DOWNTIME ALERT: wurfl;COMS ad-hoc 
check;STOPPED; Service has exited from a period of scheduled downtime

Tue Mar 29 06:30:44 HOST DOWNTIME ALERT: yada;STOPPED; Host has exited 
from a period of scheduled downtime
Tue Mar 29 09:11:27 Nagios 2.0b2 starting... (PID=5473)

tsitc> grep nagios /var/log/messages
Mar 29 06:30:44 tsitc /kernel: pid 31467 (nagios), uid 1000: exited on 
signal 11

Obviously it is easy to check whether scheduling downtime is causal; I 
will give it a go and watch.

No core file.

Yours sincerely.
