Hi All,
We are using Net-SNMP 5.3.1 version. Our EM application sends SNMP get
requests at regular intervals say 5 every minutes.
Some times SNMP agent is hanging and not responding to any queries. And the
Agent is not hanging always. It is happening only some times. We can still
see the pid of the Process. But it is not responding to any SNMP get requests.
Below is the pstack output. We are not able to understand where to fix the
problem.
# pstack core.mahesh.14395 | more

Any help or pointers on this very much appreciated.
Thanks in advance.
