Hi there,
We are having a very strange issue with net-snmp on Solaris 10 server.
snmpd dies all of the sudden, and then we try to disable the service, it goes
into maintenance mode, I have to run another disable to bring snmpd into
disabled mode, then I enable it back. It runs ok for 30 sec or so, you can see
on snoop that it is receiving UDP traffic from another hoist sent via snmpd,
then it dies. Have you guys seen behavior like that from any other user?
Also I noticed that there are 4K BOUND and 5K CLOSE_WAIT ports on netstat -an.
I also heard about the MOB cache table limitation to 1000 of those.
When it is working, i can snmpget to myself (same server)
ecweb02 [/] # /usr/local/bin/snmpget -v 2c -c Dk2twmP$ ecweb02 sysUpTime.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (259458) 0:43:14.58
When it is not, it timesout:
ecweb02 [/] #/usr/local/bin/snmpget -v 2c -c Dk2twmP$ ecweb02
sysUpTime.0
Timeout: No Response from ecweb02.
You help much appreciated.
Here is some more data:
