I am running bsnmpd with basic snmpd.config (only community and location
changed).
When there is a problem with HDD and disk disapeared from ATA channel
(eg.: disc physically removed) the bsnmpd always dumps core:
kernel: pid 1188 (bsnmpd), uid 0: exited on signal 11 (core dumped)
I see this for a long rime on all releases of 7.x and 8.x branches (i386
and amd64). I did not tested 9.x.
Is it a known bug, or should I file PR?
Do you happen to run bsnmp-ucd too? If you do then what version is it?
In bsnmp-ucd-0.3.5 I introduced a bug that lead to bsnmpd crash on a
disk detach. It has been fixed (thanks to Brian Somers) in 0.3.6.
No, I never installed bsnmpd-ucd. We are using plain bsnmpd from base
without any modules.
It is used by MRTG only for network traffic. Nothing else.
Then the backtrace might be useful.
