Nagios Support Forum

Hi,

one nagios server:
use nagios-3.2.3.tar.gz, nagios-plugins-1.4.15, nrpe-2.12.tar.gz
os: Red Hat Enterprise Linux Server release 5.7 (Tikanga)
100 nagios client :
use: nagios-plugins-1.4.15.tar.gz, nrpe-2.12.tar.gz
os :　Red Hat Enterprise Linux Server release 5.7 (Tikanga)

before 2014.9.30 , everything is ok .

2014.9.30, when I fixed the bash bug , there is a problem .
Sometimes, nagios responese info "return code of 139 is out of bounds"

I check nagios log and system log :

nagios log:
[1412737703] Warning: Return code of 139 for check of host '192.168.1.102' was out of bounds.

system log :

This problem happen randomly when I fixed the Bash bug.

Is there any other information in the log related to this segfault?

I use " tail -f /var/log/message " to check system log .
There is no more information except the segfault line .

I find "segfault at 00000000000000c0 rip 000000349e453784 ..." is repeat

I copy other log :

There sure are a number of segfaults from sh (your shell).
How did you fix the bash bug? If you updated from a repo, can you check to see if there was an additional update released for bash since then? If you didn't update from repo - how did you update bash?
