Hi,

I don't the reason for this behavior..

But, on mvl-ppc, we also observed that snmpd hangs sometimes. When we checked the strace of SNMPD at that point of time, it was stuck in the SYS_265() system call. Can you please check with strace when snmpd hangs.

Thanks,

Suresh.

Subject: SNMPD hangs after awhile

Hello all,

Currently I have Nagios set up to use SNMP 5.2.2 to perform checks on nearly 200 machines. Recently some of my SNMPD daemons started hanging and stop responding to snmp requests.
When I check with netstat, I get these results back:

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
udp 107824 0 *:snmp *:* 31154/snmpd
The Recv-Q has become insanely high (it's always 107824), which leads me to believe the SNMPD daemon has been floaded with requests somehow.
Does anyone know a workaround of some kind, or a way to flush the queue if the SNMPD daemon crashed or something?

Thanks!
