You might check out Apache::DB from cpan, it will give you a Perl debugger (much like gdb) so you can step through your code, and the third-party modules code (if in Perl) and see where things are going wrong. You might also try running your httpd with only one process ( -X I believe ) and see if it has the same behavior. I would also check out: http://perl.apache.org/docs/1.0/guide/porting.html#Sometimes_it_Works__Sometimes_it_Doesn_t Hope this helps! --------------------------------- Frank Wiles <[EMAIL PROTECTED]> http://www.wiles.org --------------------------------- -- Report problems: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html List etiquette: http://perl.apache.org/maillist/email-etiquette.html
