memory leak in 2.3.4-alpha

[Joe Schaefer <jo...@yahoo.com>]

Unfortunately all the httpd hackers in infrastructure have
wandered off the reservation, but we've been running 2.3.5
for the Apache websites for the past coupla weeks and it
has a rather serious memory leak somewhere.  That's the core
reason why we ran into those gzip encoding issues in February.


If any httpd committer familiar with Solaris 10 wants to take
a look at the server, I'd be happy to arrange access.  Just
hop on #asfinfra on freenode.

Thanks.

Looking at backtraces from brk() could help.

# /usr/sbin/dtrace -n 'syscall::brk:entry /execname == "httpd"/ {ustack();}'

Hm, on closer inspection it seems the high memory
usage we're seeing is common to both 2.3.5 and 2.2.12,
so it's likely an mod_mbox issue, which is probably infra's
ball of wax to deal with.

If anyone committer wants to help, the invitation is still
open, but this time it's for eos (another Solaris 10 host).

Aurora, the box I was talking about in the message below,
failed to survive a reboot, so the issues we've been dealing
with it in infra may not be the fault of code in httpd.
