This strange kind of segfaults is usually the syptoms of disagreements in large-file support in httpd/apr/perl. Detecting these kind of configuration problems has been discussed before, but it's not quite as easy as it sounds ;-) You can see one of the original discussions about this here: http://marc.theaimsgroup.com/?t=111686169600002&r=1&w=2 And it's evolution into a solution here: http://marc.theaimsgroup.com/?l=apache-modperl-dev&w=2&r=1&s=segfaulting+apache+in+ap_pcw_walk_files_&q=t -------------------------------------------------------------------------------- Philippe M.
