strange problem

[Karol Wiesek]

Recently i've noticed following problem that occurs on my 5.1 on sparc64.

If machine works longer than two days it's ok, it will work till
reboot/shutdown, but there is a problem, because when uptime is about two days
it sometimes freezes.

I tried to find out what could make this kind of problem but there was no signs
in logs, by turning off several features in kernel ( ipv6, mac etc. ) i've not
also find out what could make this kind of behavior.

Does anybody have the same problem?

I have Sun Ultra 5
cpu0: Sun Microsystems UltraSparc-IIi Processor (360.00 MHz CPU)
with FreeBSD 5.1-RELEASE-p10
