getting kernel panic on FreeBSD-5.1-p2

[Markus Paluschek]

I have Compaq Proliant Server 350Ml with 2 Pentium Xeon IV 2,4GHz
processors.
After installing FreeBSD-5.1, upgrading to FreeBSD-5.1-p2 by cvsup and
recompiling kernel with SMP support
I;ve download ircd-hybrid-7 sources and installed on user account after
running it and writing /restart my.ircd.server Im getting kernel panic:

Fatal trap 12: page fault while in kernel mode

syncing disks, buffers remaning... 5132 5132 5132 5131 5131 5131 5131

than system locks, need to reset.
What to do for fixing that?
