Oh yeah, I better also mention that that was the x86-64 edition of FC2 
on a dual Opteron box and to make it perfectly clear, that is a 
different box to what I have now which is just a P4 box running Centos 4 
which I keep updated and therefore Centos 4.3.

Sir, I stated the use of Centos 4.3, there are no updates for 
cyrus-sasl* available and you are naive to think that everything in 
RHEL4/Centos 4 works properly. Look at the mess Redhat made with their 
kernel vm patch for those who require performance in addition to stability.

I take offense at the notion that reporting problems with distribution 
provided software is equivalent to 'bastardizing CentOS' especially 
since I took pains to point out that the code comes from Redhat and not 
from the Centos project.

An attempt to get a backtrace gives these results:

All traces show the crash in _dl_sysinfo_int80 for those who are 
interested in licking this one. Are there any debug rpms available?
