Nick,

Thanks for the info on the alarms glitch!

Yes, we're using OS-9 ISP on a MVME147, a MVME167 and several PEP VM40/VCOMs.

We began having lots of trouble with the PEPs which beat on the net (almost
2/3's of the cpu application time is spent on net transfers).  Mostly the
networking would cease to function (no telnet, ftp, but sometimes pings work),
although once on a great while the whole machine would hang.

PEP told us about the alarm bug, but we generally aren't using alarms in our
code when the hangs occur.  So far, we've tried a newer ISP version (with yet
another version coming beta from MW), cutting down net usage, etc. I also tried
bumping up the default IRQ system stack just in case the net drivers were using
a lot of stack space. No help yet.

We have noticed that the ISP processes such as ifman eat a lot of cpu time.

best - kevin
