Starting from PHP4 I keep finding some running httpd processes. I attach to such process with gdb and always find it in chunk_free.
glibc is 2.1.2
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
Relevant (I think) config options:
httpd.conf - MaxRequestsPerChild 50 (trying to diagnose memory problems)
php.ini - memory_limit = 8M

./configure --enable-debug=no --enable-memory-limit --with-apxs=/usr/local/apache/bin/apxs --enable-versioning --with-mysql --with-gd --with-imap=/usr/local/

Does this happen with latest CVS snapshot from http://snaps.php.net/ ?

No feedback -> considered fixed in CVS. Reopen if problem
persists with soon to be released PHP 4.0.5.
