RE: snmpd memory consumption 5.7.2

Hi.  I saw a similar problem in moving to Net-SNMP 5.6.1.  The memory leak was pretty large as I recall, about 8K per trap.  Memory was consumed up to the limits of the compiler, but this was having an adverse affect on other embedded applications

It seemed to me that a new MIB had been included by default, the Notification Log MIB.  A call was being made to implement this, and that was where the memory leak was.  The Notification Log MIB wasn’t providing any benefit that I could see, so I tried unsuccessfully to omit it with a “—with-out-mibs=”NOTIFICATION_LOG_MIB” directive to the configure step.  Since that didn’t work, I commented out the call to log_notification() in the file snmpNotifyTable.c.  That worked.

Fwiw—there’s probably a more accepted way to solve this.

Subject: snmpd memory consumption 5.7.2

Hello together,

I'm using net-snmp 5.7.2 with agentx for my own agent. I actually have the problem, that when i generate a trap with my device, the memory consuption of the snmpd is growing. When i generate many traps, the memory consuption grows till 40% of physical memory and then it stops growing. The snmpd is working well so my problem is the memory consumption, the same agent compiled with net-snmp 5.3.2.2 is working without this issue. Has anybody an idea? It looks to me like a sipmle configuration problem, but i cannot find the right parameter.

Thank you all.
