Hello, I'm using Debian squeeze 64bit with snmpd 5.4.3~dfsg-2.
On this system I'm running several Cyrus IMAP server instances. Every cyrus instances is started to connect to a snmp agentx: snmp 7292 0.0 0.0 51596 4096 ? S Jul15 10:38 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd-mail20.pid -x /var/agentx/mail20 --agentxperms=775 755 root mail tcp:mail20.ugent.be The cyrus imap daemon's master process is (well was) configured to connect to /var/agentx/mail[number] From time to time my cyrus master process vanishes! This leaves the service unavailable. I have looked at this with a cyrus developper and looking at the backtrace we see that the problem lies in the integration with snmp. (gdb) bt #0 0x00007f4a56cd6013 in sendto () from /lib/libc.so.6 #1 0x00007f4a5868b1ae in ??

I can't see any pattern. I would appreciate any help to further debug this. As we don't have any snmp statistics for the time being.
