Yeah, sorry for my last mail, it was sort of stupid and
incomprehensible :( I have just checked the logs and unfortunately I
don't have the trace any more.

I was not exactly clear in my last mail, I was using vanilla
kernel with vserver patches ver. 2.1.0-rc2 (I don't know how that
relates to Gentoo as I'm using Debian in general). Now one box is
running with 2.1.0-rc4 SMP (the dual Xeon), the AMD64 is
running UP with 2.1.0-rc2 (will probably try rc4 SMP next week) and we
got a new dual-Xeon HT box (4 logical CPUs) running SMP but
unfortunately I cannot tell which vserver version is running there as
I did not build the kernel. Will ask though. Anyway, that new box is
apparently running rock-stable on permanent load of about 10
(bonnie++, make -j8 kernel builds and httperf banging at the machine,
all within 4 vservers)

Thanks a lot, I've applied 2.1.0-rc4 now. BTW, did I miss the
announcement or are they not sent here? Last time I checked, rc2 was
the newest

This is from the rc4 kernel but if I reboot the box, I'll check it on rc2 too.
