Apparently, linux-smp is rather dead, so I'll repost it here.

Subject: SMP bugs (2.4.0-ac11, 2.4.1) with traces from the serial console (fwd)
We've had quite some problems with one of our SMP servers, a dual P-III 333,
Asus mainboard.
I'll post some traces, which I got over the serial console. Machine would
normally be 99% dead in the water, no serial console input worked anymore
(eg sending a break for SysRq-u and SysRq-b would not work).
The machine is colocated, so I don't know if keyboard input was still
accepted. Userland would be quite dead, and networking would bein the worst
state imaginable. It would send out ICMP (eg ping works), and it would send
exactly one packet for each TCP connection (eg it would send syn-ack, but
then be silent forever).
When running 2.4.0-ac11 it would be reasonable stable (1-2 weeks of uptime).
On 2.4.1 it would die within hours. 2.4.2 didn't compile for me.
One of the things I noticed was that the system was also leaking fd's. I
would get messages like "VFS: file-max limit 4096 reached" and raising them
would only help for a day or so, "VFS: file-max limit 16384 reached"
This usually happened when I was doing something tough, heavy NFS stuff one
time, and heavy dns (webstats resolving an masse) at other times.
Below are the traces of the two kernels involved. If it is useful, I can
supply more data, if you tell me what else you need. But I'm fearing the
length of this email as it is.
Please CC: me on any replies, as I'm not on the linux-smp list.
Cheers,
Paul
