RE: Agentx session to master agent attempted to be re-opened.

All,
 
We observed the following message in Net-snmp-5.2.2 subagent also.
"Agentx session to master agent attempted to be re-opened."
We observed that there is a memory leak in subagent when
agentx_send_ping() function returns failure, it is not calling the
function remove_trap_session().
We have submitted a patch to solve these two issues. Following is the
link for the same.

Subject: Agentx session to master agent attempted to be re-opened.


Hi,
 
We are using Net-Snmp-5.1.1. We are observing the following message in
subagent's log.
 
"Agentx session to master agent attempted to be re-opened."
 
When we analysed the log, we found that subagent has sent an agentx ping
request to master agent. 
But subagent got the transport disconnect indication before getting the
response for ping.
When Subagent received transport disconnect indication, it unregistered
the callbacks, unregistered the alarms and 
registered an alarm to reopen the agentx session. 
And subagent found that there is no response for the ping, it
unregistered the callbacks, unregistered the alarms 
except the one registered to reopen the agentx session, closed the
session and called agentx_reopen_session() to open a new session.
New Agentx session is opened and MIBs got registered and an alarm is
registered for sending ping request.
 
Now run_alarms() is called and alarm to re-open the agentx session is
scheduled. As an agentx session already exists, it prints this message
 
"Agentx session to master agent attempted to be re-opened."
 
This alarm to reopen the agentx session got scheduled every 15 seconds
(ping time interval) and prints the above message.
 
I have the question... why the alarm to reopen the agentx session is not
un-registered ..?
Please clarify me.
 
Thanks,
suresh.
