If they've been touching the SNMP engine, I wonder if this is related to
the incorrect CPU data I've been seeing. It *looks* like Cacti's
snmpbulkwalk of the device is causing a spike which it records, but
which isn't sufficient to make it to the internal rrd. So my CPU looks
like it's running 80% constantly from the outside, and 3% from within.
Very frustrating, and no real help from MT on it, only that they can't
reproduce it with The Dude or MRTG.

I can agree that the bug is SNMP related, however I don't think it's got to
do with Memory specifically.
Similar to Bill we've been checking Ram usage (and graphing on the
Mikrotik's themselves) and haven't seen any near 100% before crashing.

We usually monitor free memory on our ROS installations. I presume we
would see the number dwindling toward zero. If we set up a trap or
threshold to alert us, I'm thinking we would be able to reboot it before
we
ran into trouble?

We've had 5.0 and 5.2 AP's where we have Dude monitoring of WDS speeds
show
memory leaks, Any ROS 5.x AP's we have show signs of this but some show
faster than others, One AP still runnning 5.2 will need to be rebooted
in
4-5 weeks before a crash, Another will need a reboot in 3 days

Hi All,
Thought I would let you guys know that MT support have confirmed a
memory
leak in ROS 5 that is caused by SNMP, Depending on router loading and
how
many SNMP get's your doing it takes a while to kick in but we have a
RB433AH
that takes about 8 days for memory to fill it and for it to crash. We
have
no word on what we can do to avoid it or when it will be fixed.
So just an FYI to everyone to keep an eye out :)
Cheers
