Package: snmpd Version: 5.4.1~dfsg-12 Severity: important
We have seen some random crashes of snmpd. The crashes happen on xen domU hosts. I managed to reproduce the crash by querying snmpd constantly. Normally the crashes happen approximately once a month. The only log message left behind after the crash is the following one. kernel: [3145305.998225] snmpd[2097]: segfault at 0 ip 7f1db543d72e sp 7fffffffcce0 error 6 in libnetsnmpmibs.so.15.1.0[7f1db5382000+118000] While trying the reproduce the crash in a controlled manner I run the snmpd under gdb. Below is the stack strace. Unfortunately, I am not a programmer nor do I know how to gdb in the most effective way so there may be some relevant information missing.
