Ouch.  I don't have any particular difficulty figuring out where the failures
are coming from - I have some ideas on what to do about them, but those lock-ups
don't make sense given the information you've supplied.  Would you try this on
2.4.9-ac4 please?

Also, the backtrace now makes sense, but just for the first 6 entries.  Now that
you have your System.map properly linked, klogd should be decoding the backtrace.
What version is your klogd?  Is your network code in modules or compiled in?

Could you supply a ps -aux that shows your hung processes?  Even better,
backtrace with SysReq.

I am running the stock klogd (1.4.0) from the redhat 7.1 install.  I'll 
give it a try with the 2.4.9-ac4 tomorrow.  The output you saw is from a 
  mostly static kernel (except for reiserfs).  Ps -aux shows a bit of 
output, but remember that it hangs after encountering the error... Mhsqd 
is one of our products.  I strongly suspect that the hung process is 
SMTPserver, which isn't shown
