General question has anyone else seen processes running under
cygwin using 100% CPU when the shouldn't.
The background is cygwin 1.5.5 I have a perl script which
monitors process cpu levels. It does this using serveral system
calls to other utils, ps, vmstat and pslist ( win32 app from
sysinternals ). The script samples every minute recording the
results.
Now 99% of the time all is fine but sometime when actually
running ( every minute ) it and the utils it spawns most notablly
pslist use 100% cpu. So much so that if you have the desktop
open it will freeze for the few seconds that its sampling for.
Its very strange once its doing it it will continue to do so for each
sample until restarted. The only pattern I can see so far is that
it tends to happen when said script is started from sub shell
script via a ssh -l user "restart.sh"
Anyone seen anything similar? Alternatively what do people
think is the best approch to find the issue? On FreeBSD truss
would be my first port of call.
