I have hundreds of checks that work flawlessly. But one check always fails, but when I cut the check from the debug.log and run it on the console, it works fine. The command in question is this:
/usr/lib/nagios/plugins/check_ipmi_sensor -H vmwsrv1-ipmi.adwin.de -L user -P
XXXXXXXXXXX -U nagios -x 123456789
IPMI Status: OK | 'System Temp'=36.00 'CPU1 Vcore'=1.22 'CPU2 Vcore'=1.34 'CPU1
DIMM'=1.52 'CPU2 DIMM'=1.52 '+1.1 V'=1.10 '+1.8 V'=1.82 '+5 V'=5.02 '+12
V'=11.87 'VTT'=1.14 '+3.3 V'=3.22 '+3.3VSB'=3.34 'VBAT'=3.22 'FAN 1'=3481.00
'FAN 2'=2500.00 'FAN 3'=3481.00 'FAN 5'=3481.00 'FAN 6'=2304.00 'FAN 7'=3600.00
'FAN 8'=3481.00
I was able to strace various subprocesses down to /usr/sbin/ipmi-sensors, which
contains this when run from the command line:
getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0
brk(0) = 0x1fa5000
brk(0x1fc6000) = 0x1fc6000
getrlimit(RLIMIT_CORE, {rlim_cur=0, rlim_max=RLIM_INFINITY}) = 0
setrlimit(RLIMIT_CORE, {rlim_cur=0, rlim_max=RLIM_INFINITY}) = 0
access("/etc/freeipmi.conf", R_OK) = -1 ENOENT (No such file or directory)
close(4294967295) = -1 EBADF (Bad file descriptor)
access("/etc/freeipmi//freeipmi.conf", R_OK) = 0
open("/etc/freeipmi//freeipmi.conf", O_RDONLY) = 3
read(3, "#", 1) = 1
read(3, "#", 1) = 1
read(3, "#", 1) = 1
And it contains this when run form icinga2:
getrlimit(RLIMIT_STACK, {rlim_cur=1024*1024, rlim_max=1024*1024}) = 0
brk(0) = 0x1ed7000
brk(0x1ef8000) = 0x1ef8000
getrlimit(RLIMIT_CORE, {rlim_cur=0, rlim_max=RLIM_INFINITY}) = 0
setrlimit(RLIMIT_CORE, {rlim_cur=0, rlim_max=RLIM_INFINITY}) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
Icinga2 is running with the option "--no-stack-rlimit". Any ideas what is
causing this and how to fix this?
