Apache 1.3.26 with mod_ssl is the webserver.  DSO support.
I have PHP 4.1.2 configured like so, which does not cause this memory problem: './configure --with-mysql  --with-apxs=/usr/local/web/apache/bin/apxs'

I currently have configured PHP 4.2.2 like so:
./configure --with-regex=php --enable-memory-limit --with-mysql=/usr/local/mysql --with-imap=../imap-2002.RC2 --with-imap-ssl --with-ttf --with-gd --enable-ftp --with-bz2=/usr --with-zlib --with-openssl --with-apxs=/usr/local/web/apache/bin/apxs --with-freetype-dir=/usr/local  --enable-gd-native-ttf --with-jpeg-dir=/usr --with-png-dir=/usr --with-pear --with-mm

and as soon as I install the new libphp4.so, and restart apache...  the new httpd processes dominate all the CPU time.  Not hideously badly, but enough so I can't let it continue.  The load goes to 7 or 8 and stays there.  
The issue goes away when the older module is replaced.
There are no compile or make errors printed that I've noticed.
What can I do to resolve this?  Is this a known problem with a certain combination of modules?
Thanks

First try with ONLY --with-apxs option. And that works, then add the options you had one by one and see after which one it starts to do this. Also, try this snapshot:

I'm pretty sure this is a dupe of:
http://bugs.php.net/bug.php?id=14870

tomki: Can you strip the GD stuff?

Instead of SIGUSR1 use SIGHUP and tail the error log, looking for "child [pid] still didn't exit" errors.

It's SOME dl issue with BSDi, but I still haven't figure it out either.

As a side note: all this goes away when you compile as a static module. If you're tight on memory, be sure to strip httpd manually after install, saves a meg or so, depending on the modules of course.

msopacua:
  It's actually not GD.  It's IMAP.
Initially I attempted to use the latest RC2, and began seeign this problem..  I've tried the 2000c and 2001a since, but no dice.  I've tried it with nothing but IMAP + mysql + apxs..  within a minute there are btwn 3 and 5 httpd processes consuming 98% of the CPU.
A problem I'm having that may be related??
The UW imapd compilation does not generate .so libraries..  and php complains after the MAKE if the dynamic libraries are not present.  I can make them manually in the c-client directory, with 'gcc -shared -o c-client.so *.o'..  
At that point the PHP compile does not complain..
 [2002-07-29 19:50 UTC] sniper@php.net
You're actually NOT supposed to compile with shared c-client. Just let us know WHAT the error is when you try
to compile with the static c-client.

 [2002-07-29 20:17 UTC] tomki at alink dot net
Hunh, ok.  Here's why I thought differently:


*** Warning: This library needs some functionality provided by -lc-client.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have.
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.
Making all in pear

Did this happen with this snapshot:

http://snaps.php.net/php4-latest.tar.gz

???

 [2002-07-29 21:06 UTC] tomki at alink dot net
It does not happen with that snapshot.  However, libphp4.so is not built..  and the 'make install' fails because that isn't found.  :)
 [2002-07-30 05:40 UTC] msopacua at idg dot nl
verified, with update gcc (2.95.3) up-to-date autotools and (g)make, against HEAD cvs.

I'm working on a libtoolized version of the imap c-client. Maybe we should fork that one as well? Especially since it will be quite some time, before Apache 2 has static module support.

tomki: if you need imap, there's no other way then compiling php as a static module.

Is this fixed in 4.2.3?

I don't know :)
Try 4.2.3 and report result back.
 [2002-09-08 03:36 UTC] tomki at alink dot net
Ok
No, it isn't.
Same issue of wanting a shared libc-client library.
I tried the snapshot, and it didn't complain about that, but failed during the make install. (I forget where, I'll try another snapshot in a couple days)

Did not work; didn't generate the .so

Is there anything in .libs/ or libs/ directory?
