Lookup during intensive IO
I am lost, I don't know what to do find the cause of the problem.
When I put the machine under IO stress the it lookup. It hapens
during backup of the machine by the network to an amanda server.
Doing tar of the filesystems can lookup the machine.
What I have done to try to isolate the problem:
- I have run memtest86 during more than one day without errors, to
catch memory errors.
- I have run burnK7 see if it was a heat problem. The CPU heated
until 82 degrees and didn't crash.
- With the CPU at 82 degrees I could compile the Linux kernel. And
off course the temperature have gone down.
- I have tried many kernels: 2.2.19, 2.4.7-686, 2.4.9-k6,
2.4.9-386. And was the same.
The hardware of the machine is:
- AMD Atlhon 900 MHz
- 256MB SRAM
- Motherboard is a ASUS A7V with VIA KT133
- A second IDE controler Promise PDC20265
- hda: Maxtor 91152D8, ATA DISK drive 11GB
- hdb: Maxtor 90648D3, ATA DISK drive 6GB UltraDMA33
- hdc: Maxtor 98196H8, ATA DISK drive 80GB UltraDMA33
- Adaptec 2940U
- scd0: Vendor: PLEXTOR Model: CD-R PX-R412C Rev: 1.07
- scd1: Vendor: PLEXTOR Model: CD-ROM PX-20TS Rev: 1.01
What can I do more to find the cause of the lookups.
