Currently, I have apache-1.3.19 loaded on a Solaris 5.7 machine with php v4.0.5 loaded as a DSO module.    My complaint is, evertime I run "/usr/local/apache-1.3.19/bin/apachectl stop", it dumps core.  

I've got other modules loaded on this apache configuration and prior to loading php, "apachectl stop" runs without a hitch.  But once I load libphp4.so, start the server, then run "apachectl stop", it dumps core.  

The odd part is, I'm able to run an "apachectl restart" and it won't dump core.  Has anyone encountered this as well?

Well, here's some system-specific info pertaining to my apache setup.  Please let me know if I can provide any other info.

I compiled apache-1.3.19 with gcc-2.95.2 on a Sun Ultra 10.  php-4.0.5 was built with the following:  mysql-3.23.37, openssl-0.9.6a, and imap-4.7uw (Univ. of Washington's version of imap).  

I don't believe imap is the source of the problem as I've been able to build previous versions of php successfully with that particular version of imap.
