Bug description:GC enabled causing huge memory allocations
Description:
------------
I'm unable to reproduce it in a small snippet, the problem occurred in a
huge code base at "random" places trough out the application. However after
setting "zend.enable_gc = Off" the problem disappeared.
The problem varied, but were all related to memory_issues of massive
allocations. Some up to 3GB:
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried
to allocate 3061525857 bytes) in [...]
Sometimes the errors were more informative:
PHP Fatal error: Allowed memory size of 209715200 bytes exhausted at
/usr/src/php-5.3.2/Zend/zend_operators.c:1243 (tried to allocate 1515870818
bytes) in [..]
And all errors were string related. They all happened on lines where some
sort of concatenation was going on, like:
$string = $value. $string ;
or with functions like str_replace():
$string = str_replace("[".$field."]", $value, $string);
* APC was not installed on the machine.
* We tried both mysqlnd and libmysql, since initially that was the biggest
difference between the development and production servers.
* PHP was source build on a debian server, the following parameter were
used: ./configure --prefix=/usr/local
--with-apxs2=/usr/local/apache2/bin/apxs --enable-soap
--with-freetype-dir=/usr --enable-gd-native-ttf --with-gd --with-zlib
--with-bz2 --enable-zip --with-mcrypt --enable-ftp --with-openssl
--with-curl --enable-mbstring --with-mysql=mysqlnd --with-mysqli=mysqlnd
--with-pdo-mysql=mysqlnd --with-ldap --with-pdo-mysql --with-sqlite
--with-tidy --enable-calendar
Actual result:
