Subject: P4 crashing under load
To: None <port-i386@netbsd.org>
From: None <rmcm@compsoft.com.au>
List: port-i386

The hardware supplier is investigating a memory fault - are ECC memory
faults logged with i386? I cannot find a reference to this in
src/sys/arch/i386.

The machine is a P4 running 1.5.2 (dmesg below) which is dropping into
the debugger 1-2 times per week, usually when under heavier load. It
is running as a server for VNC clients with Samba, PostgreSql, printing and email. I
cannot get direct access to a console, but on the 2 most recent
occasions the user reported

          - uvm_fault/kernel page fault/lpd
          - uvm_fault/awk


many thanks
