Hi,
I figured out what the problem was. The NFS mounts our machines had
were hanging, thus causing SNMP to hang when requesting data about
these storages.
I remounted the NFS mounts and all is working again.
Thought I'd let you all know.

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???

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,

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!
