There was a update on squid package today, apply it and see what happens.

Squid was reinstalled with the latest version, but still the same.

I'll try to reproduce it here.
You get this memory alert once or after squid restart alerts are frequent?

The memory alerts only shows after a Squid restart. After the initial alerts there are no more alerts. At least that is what is occurring here.

When that error occurs, Squid fails to work as a transparent proxy. Squid still works if you manually set the proxy settings in a browser for example. I disabled pfBlocker for now. Will try a few things.
-
Increase even more Firewall Maximum Table Entries in system->advanced -> firewall/NAT
not!!!! Firewall Maximum States ;)
-
PfBlocker use url tables, so it is firewall maximum table entries for sure.
Firewall maximum states are related to active connections. When you reach this value, you can't do anything on firewall.
-
After trying out a few things all is fine for now. Disabled the TBG List and left the Bluetack enabled. Also in System -> Advanced -> Firewall and NAT; Firewall Maximum Table Entries, removed that large number[9999999999999999] from there. Restarted pfBlocker and now there are no error messages and Squid works as transparent proxy, even with pfBlocker enabled. So it seems the TBG list is the cause of all these issues I was having.

You may try if you want add each TBG list until you find what list get errors.

Yes, I'm going to try that. I might spring for the i-block lists, need to do some research on that. Are the i-block lists any better than the public lists?
-
Did some testing.
With the following in the TBG list, whenever I try to enable them[one at a time], get the Fatal error below.

Note, the Bluetack list is still enabled. When testing the above.

I did, or do you mean something else?

I mean that. Sorry, I didn't saw the "[one at a time]"

No problem and guess no more lists for me :(

The are some file hacks to increase php memory limit, but it is not supported or recommended by core team.
DO IT AT YOUR OWN RISK
edit ini_set("memory_limit","128M"); to 500M in /etc/inc/config.inc file
and include ini_set('memory_limit', '490M'); on pfblocker.inc
Do not increase it to a value greater then 510M, suhosin.memory_limit is set to 512M
-

I take it a reboot is needed for these changes to take affect?
-
Not at all. There is no changes on php.ini
-
Hmm, I edited the following to test:
/etc/inc/config.inc and changed ini_set("memory_limit","128M"); to 500M
/usr/local/pkg/pfblocker.inc and added ini_set('memory_limit', '490M');
Then tried to enable the TBG list, but still get the Fatal error. Did I do something wrong?
-
Not sure, I did it on a x64 virtual machine and I do not get php limit errors.
All files are uploaded.
EDIT
With all these large files, my virtual machine gets 100% cpu for more then a minute and even with a very large table size, it reach virtual machine memory limit (384Mb).
