Subject: Question about scheduling in 2.4.20

Hi,
I have a question about scheduling latencies in 2.4.20. We are seeing
that our
process (started with default priority, normal fork, exec) is not
scheduled
on the CPU for 4 seconds (from our kernel traces). Is that possible
under
heavy load ? We believe the process is still alive but I wanted to know
if
anybody has an idea from experimental results, about the worst case
scenario.
>From syscall trace, we also know that the process is not inside any
blocking
system call.

Thanks,
Ravi
