Package: php5-mysql
Version: 5.2.6.dfsg.1-1+lenny4
Severity: normal

After I install php5-mysql, Apache server uses about 80mb memory.
MySQL Server uses about 100mb memory and the php5-mysql uses another 100mb
of memory in Apache2 server.
When I remove the php5-mysql package and restart my system, Apache2 server
use just 18mb memory.
I have configured MySQL Server to use less memory (30mb) (optimizing
/etc/mysql/my.cnf) and reboot my system, but php5-mysql loads 100mb of
memory on Apache server in this situtaion too.
I have checked it on 3 another systems and the same result occurs.
I have tested it on ubuntu and the same problem occurs.
I have tested it on Lighttpd server and the same result occurs.
I am using the latest version on Apache2  :  apache2 (2.2.9-10+lenny6)
