I've just seen thread "Vanishing Requests", and it looks quite close to what
I've witnessed.
mod_log_forensic was suggested in this thread above, so I followed this
suggestion and enabled it.
I restarted Apache and ran ApacheBench twice on a (big) Perl resource with 4
simultaneous requests. Some requests get in Apache but are never responded
back... See IDs Ce7WPqwaKB0AAB4ILmYAAAD2 and DKPMyKwaKB0AAB4ILmoAAAD1 in the
log file below.
This behaviour occurs also on the simplistic Perl script I described in my
original post.
Any suggestion, or steps I can do to troubleshoot further?
Thanks,
Pascal.
