Re: [SLE] HELP: Konqueror 3.2 hangs SuSE 2.4.21-202-smp4G in 'ps uax'

First thing I would check is memory. Run memtest86 for several hours if
any errors appear remove or replace the offending memory. Then look for
other problems. Every time I've had this kind of unreproduceable random
error it's been a bad memory module.
