JOBCL

[Ed Loehr]

Performance problem mystery here. We have a C program running as a CGI under Apache 1.3.33 on a fairly heavily loaded HPUX 11.00 9000/800 box. The program normally takes 10s to run, but very occasionally, takes 4 minutes. We caught one such run and saw that for the first 2 minutes, glance reported a proc_stop_reason of PIPE, and then for the second half, it was JOBCL.

The Apache children startup with a pipe into apache's log rotation program.

The delays as identified by log message timestamps do not seem consistent with slow program statement execution. We're wondering if it is delaying in writing to the pipe or possibly to the client? Any ideas?

After further review, this is looking like a network issue.
