There's one running now, occupying full CPU, and has been running for 45 mins and counting. It comes from this: bugzilla 25689 25675 25689 0 1 17:31 ? 00:00:00 /qmail/bin/preline sh -c /www/gcc/bugzilla/email_in.pl -v 2>>/sourceware/bugzilla/email_in.log || exit 99 Presumably started directly from qmail. I tried stracing the perl script instance itself, but whatever it's doing is all user space. It seems too much of a coincidence that it's there at the top when you looked and when I looked. The log at this time includes: Comments cannot be longer than 65535 characters. which seems fair enough as a one-off, except this log message seems to get triggered a lot - about once an hour, which doesn't seem right. Also: SENDER=gcc-bugzilla@gcc.gnu.org which implies bugzilla was the one sending the mail. Has the script got stuck, perhaps sending ever larger email in a loop? Or is someone abusing it? It's hard for me to see what the email is it's dealing with. Perhaps someone more familiar with bugzilla can work out where (or if) it spools it temporarily.
