[php-maint] Bug#577009: php5-cgi: php-cgi uses 500+ mb memory

[Olaf van der Spek]

Package: php5-cgi
Version: 5.3.1-5
Severity: serious
Justification: Memory leaks might affect the entire system

Hi,

I'm not sure why php is using so much memory. The system has 8 gb real and 4 gb swap and the OOM killer has been invoked several times already.

/etc/php5/cgi/php.ini:
memory_limit = 128M
