        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 ;)

                Your new system is probably coming with some hyper trash like Windows 8

                  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.

                    TBG list:

                      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.

                          Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 8650655 bytes) in /usr/local/pkg/pfblocker.inc on line 268

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

                                    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?

                                          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).
