Bug#421557: apache2: increasing memory usage
Package: apache2
Version: 2.2.3-4
Severity: normal
Apache2's memory usage on a low traffic server keeps on increasing until it brings the
whole server the down.
Starts with:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 23865 0.1 1.6 23076 8448 ? Ss 04:44 0:00 /usr/sbin/apache2 -k start

www-data 23877 0.0 0.8 23076 4072 ? S 04:44 0:00 /usr/sbin/apache2 -k start
A bit later:

www-data 18779 0.1 6.1 46780 31148 ? S Apr29 0:31 /usr/sbin/apache2 -k start
www-data 18781 0.0 6.1 46968 31532 ? S Apr29 0:21 /usr/sbin/apache2 -k start
www-data 18782 0.1 5.7 44612 29160 ? S Apr29 0:21 /usr/sbin/apache2 -k start
The installation is quite standard, with modules php5, psql auth, and webdav enabled.
Cheers,
Chris.
