Hi all,
I got following page fault in FreeBSD 5.3 on IBM e325 with Dual AMD64
2.2GHz, 4GB RAM and ServeRAID 6M SCSI
controller.
FreeBSD publicc.ub.mng.net 5.3-STABLE FreeBSD 5.3-STABLE #10: Mon Nov 22
09:19:35 ULAT 2004 root at publica.ub.mng.net:/usr/obj/usr/src/sys/AMD amd64
I compiled kernel with following options:
# SMP support
options SMP
options MAXDSIZ=(1024UL*1024*1024)
options MAXSSIZ=(128UL*1024*1024)
options DFLDSIZ=(1024UL*1024*1024)
options PREEMPTION
I'm using apache+mod_ssl-1.3.33+2.8.22, clamav-0.80, exim-4.43+28 and
mysql-server-4.0.22.
It is web mail server with mysql database backend.
It seems like following page fault occurs when people accesses web intensively.

Is it known problem or should I post it to freebsd-bugs list? How to solve
this problem?
Is it related to ips driver?
If somebody wants to make closer look into the problem I can give an shell
account on this server.
thanks in advance,
Ganbold
