> Apache 2.2.22-13+deb7u1(latest debian stable version) have the issue that may
> result in memory leak.
> Logrotate would use apache2 reload to reload the service after log rotated.
> But the memory used by apache2 increased after each reload, which can be a
> problem for limited memory VR.
> Here is how I measure the memory:
> root@r-4-VM:~# for i in `ps -eo comm,pid|awk '$1=="apache2"
> { print $2 }'`; do pmap $i|tail -n 1; done
> total 85680K
> total 84916K
> total 309108K
> total 309108K
> root@r-4-VM:~# i=0; while [ $i -lt 356 ] ; do /etc/init.d/apache2 reload 2>1
> > /dev/null; sleep 1; i=$(($i+1)); done
> root@r-4-VM:~# for i in `ps -eo comm,pid|awk '$1=="apache2" { print $2 }
> '`; do pmap $i|tail -n 1; done
> total 120552K
> total 344576K
