Problem
-----------
The SNMP master agents gets to a point where it does not respond to any
requests.
Problem analysis
--------------------------
1) It happens after some Set operations on a MIB item supported by a
sub-agent.
2) The master agent process is still alive, and it still receives
packets.
3) The master agent defers processing of incoming packets (including GET
on mib2 item, supported by the master agent itself)
because it is processing a Set operation:
snmpd.log part
-----------------------
trace: netsnmp_handle_request(): snmp_agent.c, 3020:
snmp_agent: request queued while processing set, asp = 0x1010aa78
trace: handle_snmp_packet(): snmp_agent.c, 1839:
snmp_agent: end of handle_snmp_packet, asp = 0x10109000
4) The agent is stuck in this state forever.
5) I guess some error occurred at the sub-agent. but it should not
affect the master so severely.
Solution:
------------
Unknown....Any ideas?
Thanks,
Erez.
