Hi
Jeffrey,
As the
following statements show that open call is returned with error ENOENT, snmpd
didn't get stuck at this function call.
Regards,
Suresh.
Thanks Suresh.
I ran
strace and for some reason, it cleaned out the queue...
I'm not exactly
sure why snmpd gets stuck. When I keep strace open and I send a snmpwalk to
the host and it starts to hang again. I see alot of functions being called,
but the only somewhat error-like notification I can find is this one:
open("/etc/hosts.allow", O_RDONLY)
= -1 ENOENT (No such file or directory)
open("/etc/hosts.deny",
O_RDONLY) = -1 ENOENT (No such file or
directory)
Which is correct, cause they don't exist. Could
snmpd really crash because of this???

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.
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
