I was generating heavy disk usage through database and astronomical data reductions. My machine (dual AMD) would suddenly hang. No new jobs would run, just increase the load, until I reboot the machine. I solved my problems by creating a 128Mb ram disk (using EXT2) for the temp data produced my reduction runs. I believe JFS was to blame, not hardware, but you never know... Cheers, Rob -- 20:22:27 up 12 days, 10:13, 4 users, load average: 2.00, 2.01, 2.03
