I am running bsnmpd with basic snmpd.config (only community and location

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.
Ok, I was able to to reproduce this under qemu doing
atacontrol detach ata1
[...]
and it crashes in disk_OS_get_ATA_disks() when the removed map entry
is dereferenced.
I am attaching the patch that fixes the issue for me.
I am glad to read that you found the bug!
The fix (patch) seems trivial - will it be commited / MFCed? :)
Thank you for your work on this problem!
