While I can't say I truly see the correlation, you definitely know more
about how it works then me. I've cvsupp'd and upped it to 1000. One
question I have, is what exactly -are- pv's?
The machine itself isn't under too much load during the testing, and
definitely does not used a lot of shared memory. During one of the tests
yesterday (c89) it was doing ~8000 execs per minute, with a load of
0.23. I've also got plenty of RAM left over. Here is what it currently
looks like:
last pid: 7121; load averages: 0.75, 0.31,
0.15 up 0+00:16:15 09:21:55
59 processes: 3 running, 56 sleeping
CPU states: 36.0% user, 0.0% nice, 63.2% system, 0.8% interrupt, 0.0%
idle
Mem: 57M Active, 8412K Inact, 16M Wired, 2292K Cache, 9628K Buf, 8280K
Free
Swap: 786M Total, 22M Used, 764M Free, 2% Inuse
This is basically X, Netscape, and 5800 exec()'s a minute.
I've got debugging in my kernel, and I'll send you full results if and
when it crashes again.
