Hi Ray,

Can you please apply the patch I recently posted and report
back.

http://marc.theaimsgroup.com/?l=linux-kernel&m=109926628920398

The patch fixes a bug reported earlier. However, earlier
oops were triggered at mm/prio_tree.c:538.

I haven't looked at the trace carefully. I will do so.
Please report back if the previous patch fixes your problem.

Thanks,
Rajesh

Running on an HP DL140, w/ Dual 2.4GHz Xeon's.  1GB of ECC DDR.  Fedora
Core 2.

This server operates as a PPTP Concentrator running the PoPToP server
(1.2.1) along with pppd 2.4.3.  We have tried this system using both
the onboard Broadcom gigabit NIC's as well as a dual Intel EEPro 100.

Usually within 24 hours of bootup, the following oops occurs:

The system continues to function for approxiamately another minute.  I
see messages such as the following on the console repeatedly:

dst cache overflow

Eventually the system becomes completely unresponsive.  When I hit the
power button, ACPI tries to power down the system, but hangs after
killing a few processes and I must hard reset it.

I do not think this is bad hardware as we have approximately 11
DL140's and this will happen on all of them although more quickly on
the ones with higher user load (network traffic, CPU usage, etc).

Hoping someone can give me some suggestions if this is more likely to be a
hardware issue... just can't imagine getting that many bad servers. :)

Thanks in advance.
