Hello, We are experiencing a lot of system crashes on our machines and were wondering if anyone else had similar experiences or could shed some light as to what the problem may be. We have run both the RH 2.2.10 and 2.2.12 kernel (smp) on these machines with the same result. The hardware is:
2x PIII 500 512MB ECC memory 6.4GB Seagate ST36421A system disk (IDE, bus 0) 2x 17GB Maxtor 91700U5 (6800 series) data disks (IDE, bus 1) Supermicro P6 DBE/DGE Motherboard Intel eepro 100 Network card
The crash message we usually see is:

We are running the machines fairly hard (~98% cpu, hard disk activity about once per hour lasting anywhere from a couple of minutes to 15 minutes). We have also seen the machine swap a little. When we reduce the load on the machine, we seem to be a little more stable. We are running the seti program (from seti@home), bonnie (the disk bench test) and netttest (from NCSA) concurrently.
Thank you for your time, Ray
