>Summary: ipAddressTable memory leak; related to vlan-interfaces?

Initial Comment:
Fedora Core 5 i386
Linux kernel 2.6.16-1.2133_FC5smp
net-snmp-5.3.1.0-6 (recompiled last package from rawhide)
net-snmp recompiled without optimization.

This machine is used as a router with about 20 vlan
interfaces. snmpd binds to a address connected to
lo-interface which is announced through OSPF with quagga.

snmpd leaks memory, within a month the process can grow
up to 800-900M before I have to kill it. On FC5 servers
without vlan-interfaces, snmpd can run for months and
still be 20M of memory size.

I've run snmpd through valgrind for 5-6 hours and it
complains over memory allocation error. I'm attaching
that log.

gaupe, can you also try the patch here:

http://sourceforge.net/tracker/index.php?func=detail&aid=1596638&group_id=12694&atid=112694

And once you have both these applied, run again with valgrind and attach
the results (or come find me in #net-snmp on chat.freenode.net).

Thanks!

Seems like I'm still having leakage, the process grew to 43M in a day.

Whould a new output and/or upgrading to 5.4 be helpful?

I've applied this against 5.3.1 and compiled it, will try running it for a
couple of days and see how this behaves.
