[Tue Oct  5 02:18:10 1999] [notice] Apache/1.3.9 (Unix) PHP/3.0.12 mod_perl/1.21 mod_frontpage/ mod_ssl/2.4.5 OpenSSL/0.9.4 configured -- resuming normal operations
[Tue Oct  5 02:18:14 1999] [notice] child pid 88941 exit signal Segmentation fault (11)

I have seen a similar bug under RedHat 6 I believe, and it appears that he is also running fp and mod_ssl, don't know any connection here.  Was working fine before, and now it appears to be having major problems (well, all PHP3 pages cause it to dump).  I am not sure what would be causing this.

I have successfully narrowed this down to the mod_frontpage module, 
since when I remove that everything works properly.  As soon as I can find a
patch I'll post the resolution to this bug, and hopefully someone will close it.

Thank you for taking the time to report a problem with PHP.
Unfortunately, PHP 3 is no longer supported. Please download
the latest version of PHP 4 from

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
