Thanks for the details John, much appreciated.
With debug version of nss I now see all symbols ...
Core was generated by `/usr/sbin/httpd.worker'.

I already searched bugzilla, but did not find a related issue yet.
Unfortunatley I'm not too familiar with C, looking at 'error.c' does
this mean 'header' is null?
Thanks again,
Bernhard

Hi experts, may I ask how I can find out where NSS dumps core?
gdb backtrace of the core (performed on the target machine) does not
show the symbols ..

Would it help to load the debug version of the libs?
You want to install the debug information package for nss. All debugging
info packages end in -debuginfo suffix. You need to have the debuginfo
repo enabled in your yum configuration file or use the enablerepo arg to
yum. Look in your yum configuration file to see the exact name on your
system.
On my system (F18) the command would be
% sudo yum --enablerepo updates-debuginfo install nss-debuginfo
-Or- when you fire up gdb it will give you a command to install the
necessary debug info, just copy the command and execute it in a shell.
