pfSense

I have been using pfsense for over 2 years now and I love it (master and slave virtualized under ESXi 5.1).
I am using pfblocker 2.1 and have not had much trouble with it until last week when I started to get the error:

[ There were error(s) loading the rules: /tmp/rules.debug:41: cannot define table pfBlockerLevel2: Cannot allocate memory - The line in question reads [41]: table persist file /var/db/aliastables/pfBlockerLevel2.txt]

--------------------------------------------------------------------------
I already tried some very high values for the Firewall Maximum Table Entries with no success (System - Advanced - Firewall Maximum Table Entries = 999999999)
My previous value was 4000000 and it was working fine.

This happens with no changes made to the pfsense config: The error comes up if I update to any build after: Thu Aug 1 19:39:40 EDT 2013

I also went ahead and configured 2 GB Memory (instead of 1 GB that was working fine until last week), with no success either.

I also tried changing the PHP memory (/etc/inc/config.inc) from 256M to 512M, with no success either.
