PHP version: 5.1.6
PHP Bug Type: Scripting Engine problem
Bug description: Memory Leak
Description:
------------
PHP 5.1.6 compiled and installed without issues.
However when procedures call sybase functions and after few minutes. PHP
complain with not enough memory.
PHP seem unable to read all the script, also unable to address the
variables properly.
At beggining gave "fatal errors" due to lack of memory even with 200Mb has
memory limit (raised from its default value).
After recompiling php 5.1.6 for 2nd time, I'm now getting the following
errors, and lack of memory (200mb limit) message is now rare to appear.
Warning: Unknown list entry type in request shutdown (0) in
lib/lib_syb_sessions.php on line 61
Warning: Unknown list entry type in request shutdown (0) in
/lib/lib_syb_sessions.php on line 42
PHP 5.1.6 was compiled with the following parameters:
PHPHOME=/opt/php
APACHEHOME=/opt/apache
cat /dev/null > conf.log
export PATH=$PATH:/var/MailRoot/bin
./configure --prefix=$PHPHOME \
--bindir=$PHPHOME/bin \
--libdir=$PHPHOME/lib \
--with-config-file-path=$PHPHOME/conf \
--with-apache2=$APACHEHOME/ \
--with-apxs2=$APACHEHOME/bin/apxs \
--with-sfw=/usr/sfw \
--with-jpeg \
--with-jpeg-dir=/usr/local \
--with-png \
--with-png-dir=/usr/local \
--with-ftp \
--with-zlib-dir=/usr/local \
--enable-magic-quotes \
--enable-safe-mode \
--enable-sockets \
--enable-track-vars \
--enable-trans-sid \
--enable-memory-limit \
--enable-calendar \
--with-pgsql=/opt/pgsql \
--with-mysql-dir=/opt/mysql \
--with-sybase-ct=$SYBASE/$SYBASE_OCS \
--enable-static=sybase-ct \
--enable-mbstring
I have reviewed the procedure few times and I can't find any glitch that
could cause such behaviour.
I'm now compiling the latest 5.2* from dev's cvs to see if this issue is
solved. Cheers

Expected result:
----------------
No fatal errors with lack of memory (im now using 200Mb) where in previous
versions I used the default value.
The variables showing the correct content (not empty content or values
mixed between vars).
