My advice is to contact support.  I had many of those issues when I first
installed 5.1, but with a few patches here and there, netmon stablized (its
rock solid now), performance is excellent.  Who knows if 5.1.1 will fix all
those problems, but if you have crashing daemons, you need to call Tivoli
and get an efix, or wait for the 5.1.1 patch.

>Dear netmon-colleagues,
>since migration from NV4 to NV5.1 my netmon-life has changed.
>Fact: network-load produced by netmon has increased (NV4 avg. 30
packets/sec,
>NV5.1 avg. 50 packets/sec)
>Fact: network-load produced by netmon more often peaks out (150 packets/sec
>and more) under NV5.1
>Fact: ovsnmp.conf has become a highly delicate playground
>Fact: netmon under NV5.1 dies more often than under NV4 (especially if
>stopped and restarted with hundreds of nodes down)
>Fact: running a script every 10 minutes and (besides other stuff) checking
if
>netmon is still alive (and restarting it if necessary) was just a neat idea
>under NV4, but has become a necessity under NV5.1
>Any kind of consolation and/or advice welcome.
>Thanks for listening, Ralph.
