What's even weirder is that the process gets that far. Did you play

If so, set it lower, so you can at least have the machine in a
usable state at
all times. 4G should be enough for any process and should give
enough time
for you to spot the leak and get a ktrace.
Nope, I haven't tweaked any kernel settings, just using the generic
DEFAULT amd64 kernel. I've been way about tweaking settings
because
I don't fully understand what the 'correct' values for my setup are.
Could you show kenv kern.maxdsiz and if unset limits -H -d? Looks
like it's
32G on my 6.x amd64, in which case setting it is a good idea.
echo 'kern.maxdsiz="8G"' >> /boot/loader.conf
echo 'kern.defdsiz="4G"' >> /boot/loader.conf
Thank you for helping me. The earlier suggestion of toggling
Perl Malloc didn't work, nor did syncing sources and installing new
kernel and new world which is what I did lsat night.
As for kernel settings, I don't have anything in my loader.conf,
and I'm not entirely sure how to show things that aren't sysctls, as
this one doesn't seem to be:
celebrian# sysctl -a | grep kern.maxdsiz
celebrian# sysctl -a | grep kern.defdsiz
celebrian#
Ok sadly that didn't seem to do much:
celebrian# cat /boot/loader.conf
kern.maxdsiz="8G"
kern.defdsiz="4G"
celebrian#
I rebooted, but still see my memory being chewed up. Almost
immediately after booting, one of my spamassassin processes spun out
of control. Here's the top with it eating 16 gigs of memory:
PID UID THR PRI NICE SIZE RES STATE C TIME WCPU
COMMAND
1611 1030 1 68 0 15062M 818M CPU2 2 0:44 20.65%
perl5.8.9
and from dmesg:
<snip>
swap_pager_getswapspace(16): failed
swap_pager_getswapspace(16): failed
swap_pager_getswapspace(16): failed
swap_pager_getswapspace(16): failed
swap_pager_getswapspace(3): failed
swap_pager_getswapspace(16): failed
pid 1611 (perl5.8.9), uid 1030, was killed: out of swap space
The computer gets pretty unresponsive during this, unless swapoff my
swap, then the process eats the memory faster and gets killed
faster. Did I type in the wrong variables?
