Default Optimize your fail2ban memory use by 90%.

The solution turns out to be a one-liner on Debian Lenny

append the ulimit command to /etc/default/fail2ban file.

Add (to the file) on last line :

"ulimit -s 256"

Using this sets the default stack size for the Python instances running fail2ban to 256 KB and lowers the memory consumption of fail2ban approximately by a factor of 10.

I had 256mb use -> now less than 20.
