Hello all=2C
I was running FreeBSD 9.1 Stable on my server and I decided t=
o upgrade to 10 STABLE two weeks ago.
=20
The upgrade worked fine=2C but then the server was randomly crashing many t=
imes a day.=20
=20
I tried to upgrade to another 10 STABLE version and it did the same.
=20
I had to revert to 9.2-STABLE (r262480) and everything is fine with this ve=
rsion.
=20
Here is a summary (GENERIC KERNEL + PF & ALTQ):
