Hello,

I get a loop of OOPSes from httpd and the system locks in this loop. The distro
is Redhat 8.0, the machine is XP 2200+ on a VIA KT400 chipset with SCSI Adaptec.
This happens after 3 or 4 days of uptime.. the machine has 1GB of ram and it is
intensively used. I think the same OOPS I was getting with previous kernel releases
also ( from 2.4.19 up to this rc I have now )

ksymoops 2.4.5 on i686 2.4.21-rc6.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-rc6/ (default)
     -m /boot/System.map-2.4.21-rc6 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
