RE: SNMPD hangs after awhile

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!

-Jeffrey
