Re: snmpinform and not in time window

Hi Folks,

I did enable debug while sending inform

command : snmptrap -Dall -t 6 -v 3 -Ci -n "" -a MD5 -A 123password  -l
authNoPriv -u testinform 172.16.1.10 69 .1.3.6.1.4.1.8072.2.3.1
.1.3.6.1.4.1.8072.2.1.1 i 44

Last log is "sess_select: blocking:no session requests or alarms." and
'snmptrap' get stuck , has to kill the process manually.
I need some clue regarding above log.

Thanks,
Pushpa.T
