We are seeing a problem which may or may not be related. I have attached a
piece of the trap log showing the problem. Margit/Leslie... is this what you
are seeing as well? I am working with Raleigh and they are not able to
recreate this in their lab. We are at NetView 5.1.1 on AIX 4.3.2, and MLM
5.1.1 on NT 4.0 SP4.
As you can see from the log, when we restart midmand it sends in a bunch of
status traps, one for each device it manages - this is expected. One minute
later it sends in the same set of traps again, even though nothing changes.
Occasionally it will repeat this cycle over and over, sending in a complete
set of status traps every polling interval. Before the status traps we also
see some strange traps indicating that the alias and status monitoring
tables have changed to an invalid state.
Here is the log extract:

They told me to get the efix for APAR IY00707. It is about
repetitive traps.

Can you tell us the number of this e-fix?

Thema: Re: MLM multiple status update traps
I have been told that there is an efix out for a problem
with excess status traps, and it goes on after the MLM
update in 5.1.1, so you might want to call Support. I will
be trying it out at next week's customer. Also make
sure you don't have multiple entries in the trap destination
table for each MLM, and have not also set the trap destination
in the /etc/snmpd.conf file on the MLMs.
Cordially,

My client is seeing a problem where their MLMs are sending in multiple
status traps for each interface they manage each polling cycle. This does
not happen all the time, nor does it come from the same MLM all the time.
When hit happens It is causing some severe performance problems since it
can
send in several thousand traps every update cycle. The problem has been
reported to IBM, but I thought I would also ask on this forum if anyone has
seen this and, if so, how it was fixed.
The MLMs are version 5.1.1 running on Windows NT 4.0. NetView is version
5.1.1 also, but running on AIX 4.x.
