A nice detailed leak report. Coders, can you please investigate?
Thanks,
Mike

Ok we have had a further revelation after much testing we were able to
work out that there is one particular OID that is leaking 255 bytes of data
each time you run snmpwalk the oid in particular is:
.1.3.6.1.2.1.88.1.4.3.1.3.6.95.115.110.109.112.100.95.109.116.101.84.114.105.103.103.101.114.82.105.115.105.110.103
or its shorter name is
DISMAN-EVENT-MIB::mteEventNotificationObjects."_snmpd".'_mteTriggerRising'
the result of which is -
DISMAN-EVENT-MIB::mteEventNotificationObjects."_snmpd".'_mteTriggerRising' =
STRING: _triggerFire
we can quite happily run snmpwalk above and below this OID and get
consistent memory usage with no sign of a leak.
What we cant quite work out is what function is failing to free the
memory after its run.
any help on how to debug this further would be much appreciated.

Run snmpd without the dlmod for the LVS
module and try the same test. If there is no memory leak, then the problem is
with with the LVS module, and you'll have to get support from them. If not,
let us know.
HTH,
