I keep getting these messages in the system log:

But in the Dashboard everything looks good.

Increase even more Firewall Maximum Table Entries in system->advanced -> firewall/NAT
-
Ok, will try that. Now is at 3000000, will try with 4000000.
Edit: with 4000000 still getting those messages. Will keep trying until I find a number that works and report back.
-
Don't forget to see memory use in dashboard. If you are getting more then 80% may be time for an upgrade or smaller lists.
-
Memory is at 44% at the moment, I should have plenty of headroom.
-
Personally I took mine up to a high value that would never be reached (something like 9999999999999999 or similar). I did this for several reasons.
No memory is allocated based on this number and it makes it easy to increase my table usage without trying to find a limit that will work. So it doesn't cost you anything and this ensures that no matter how many lists I use I won't run into any issue. Just in case someone is wondering my system only has 2GB of mem which is more than enough. -
I was trying to do it incrementally, but that is not working. Got up to 15000000, but then saw your post. So I'm going to try that large number[9999999999999999].

Are you sure you are not reading an old alert?
BTW, if a really large value does not exaust memory, It's an excelent option to prevent errors.

Yes, I was making sure they where not old. I have 4GB in this box. Current memory usage:
Mem: 603M Active, 67M Inact, 1151M Wired, 1048K Cache, 406M Buf, 1991M Free
Swap: 8192M Total, 8192M FreeWhen I initially click on save, it all works fine for a few minutes[~2]. Then after a random amount of time, clicking different menus to check the settings the error pops back up. At first after using 9999999999999999; I was still getting the error. It has now been ~19 minutes since the last error message. Will keep my on it too see if the error comes back. If the error comes back, I will try deleting the offending list and re adding it, to see if that helps.
Thanks for the help!

Check on widget if were changes on amount of cidrs applied.
CIDRs are get from applied file and package count from firewall tables.

IP-Blocklist injects a large number like that to /tmp/rules.debug at the top to ensure no matter how many lists a user has there won't be any errors. So with pfBlocker, even though it's a manual process, I add that large number.
-
The CIDRs are the same as in the screenshot I posted above:
pfBlockerBluetack 761470
pfBlockerTBG 1262743It has been ~35 minutes and no new errors :) I'm crossing my fingers ;)
-
I need to improve lists size check to reduce this kind of issues or change error message suggesting tommyboy180 large configuration.
It's in my 'todo list when time permits' ;)

Needed to restart Squid and the got an alert with the error.
EDIT: Every time Squid is restarted is when the error occurs. I was messing with Squid yesterday, but did not put it together until now.
-
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.
