Hi,
I'm running an webserver on an Alpha system (LCA PCI-33 @166MHz)
The machine has two ethernet boards (RTL8139) one is used to connect to my ISP and the other to connect to a database server.
When I performed some 'heavy' nfs filecopying (read: backup the html stuff to the database machine) I got the following messages in the logs:
portmap: RPC call returned error 61 RPC: task of released request still queued! RPC: (task is on xprt_pending) lca: machine check (la=0xfffffc00002084d0,pc=0xfffffc000042fa50)
Reason: access to non-existent memory (long frame): reason: fffffffffffffff8 exc_addr: fffffc000042fa50 dc_stat: 3 car: 403cd251 A read error to memory occurred at address 3000000 Several other uncorrectable errors occurred.

this is how /proc/pci looks like:
PCI devices found: Bus 0, device 6, function 0: Non-VGA device: NCR 53c810 (rev 1). Medium devsel. IRQ 11. Master Capable. Latency=32. I/O at 0x8000 [0x8001].

How should I interpret 'Attempted to access non-existent memory', normally this would result in a segfault wouldn't it ? Is this serious hardware trouble or what ?
The system has 48 Mb RAM.
