I wasn't sure who to send this to so I sent it both the documentation and
ksymopps readme addresses.
I suspect my problem is with my Qunatum Bigfoot 6.4G hard drive and the swap
file partition. This system runs fine 24x7 until I try to run BladeEnc or
Encode or some heavy encoding software. FWIW, this is a Redhat 6.0 install.
Below is both the output in /var/log/messages and the ksymoops output. If
this has nothing to do with the kernel then let me know and i'll do more
posting on Usenet.
TIA,
Jeff Volckaert
