Classification: UNCLASSIFIED Caveats: NONE Thanks for the suggestions, Armin.
The svn version of MapServer did not fix the issue. I also tried php 5.2 as a apache module with the same results. I upgraded my php version to 5.3.10 and then recompiled Mapserver 6.0.1 against it and this fixed the issue. Unfortunately without the ability to dynamically load extensions in php 5.3, I believe I will have to run the older versions of pmapper/mapscript on a separate host until I finish all the upgrade work. Once again thanks for your help.

I never use any more PHP as CGI, so I cannot say anything specifically to that. Quite likely that running as CGI Apache does not catch and log errors from the CGI that crashed. If possible try also PHP as Apache module. Another thing you could try is the debugging possibilities with PHP and gdb https://bugs.php.net/bugs-generating-backtrace.php Mapserver 6 had/has(?) some strange bugs in PHP Mapscript which can appear just under certain circumstances, more often with PHP 5.2 than 5.3 (I guess developers mainly used 5.3 for developments). If you can, please try to compile the SVN version of Mapserver 6 https://svn.osgeo.org/mapserver/branches/branch-6-0/mapserver/ It should have some backported bug fixes that prevented Mapscript to work properly in some cases. Maybe this solves your problems.
