Confirmed...
After removing:
kern.maxdsiz=3D"2048M"
=46rom our /boot/loader.conf
Our system has been functioning fine since. Our dcc server has been in =
service for some time, since FreeBSD 4.x and has been upgraded to 6.x =
and 7.x previously. It was not until we upgraded to 8.x (8.1 as =
noticed) where we saw this problem.
I am unaware if kern.maxdsiz is needed now, but I believe it was needed =
at one time under 4.x as the kernel was killing the process after it =
grew over 512MB. It does not seem to have that effect now... The =
default maxdsiz in 8.x is still 512MB under i386, so it looks like the =
behavior was changed between 7.x and 8.x.
