Something wrong in stable 5.3?

[Eugene M. Minkovskii]

Hi!

I'm confusing now: about a month ago I have upgrated from FreeBSD
5.2.1 to stable 5.3. Since this moment strange things have been
happens on my PC. Usually system works Ok, and can be run as long
as I need without errors. But sometime, (after a little time
after the boot) all begin crashed (core dump --- signal 11).
Crashed base utility, like `cat', `sh' etc.

Today I have cvsup'ed to stable 5.3 again, and build world again,
but problem don't go away.

I don't understand what I should do to detect source of problem...

Have you any idea?
