Run the following command to find the pid

ps aux | grep pfblockerng.php

Example output:

Then to kill the process:

kill -9 46898

This stops it yes however it happens again next time cron runs

also my original error is still happening

I've even tried removing pfblockerNG and reinstalling and this doesn't help either.

Did you set the

pfSense / Advanced / Firewall-NAT / Firewall Maximum Table Entries

to 10000000 ?

jwalhous

It's set to 14000000 and I have also tried 10000000, error still happening every now and then.
Thanks for you help with this :-)

What's the memory usage on the FW (Status / Monitoring : System Memory) ?
What's the pfsense version, pfblockerNG version, CPU type etc?

jwalhous

Hi,
Running latest versions of everything.
Pfsense is running in a vm on a dell r710 server using xenserver 7

4 cores and 2 gig of ram, currently its using 47% of the ram.

Jamie

Anyone ? this error is annoying and I assume causing pfBlockerNG to not function correctly

RonpfS

You don't have much memory, on my 2.5GB system, in the last 2 days, free memory is 17-35%.
Did you look at the pfblockerng.log ? system log?
Double the Firewall Maximum Table Entries until the rules loads.

jwalhous

Increased Ram to 4gb, no difference error still occurs.
I can't see any error in the pfblockerng.log

Cheers

What does this command report?

wc -l /var/db/aliastables/*.txt | sort -n

Have you tried unchecking "Keep Settings", and Disabling/Enabling the package to see if that clears this issue? (Don't forget to re-enable "keep settings")…

Failing the above, you might also want to download/update the MaxMind database to see if that fixes your issue:

php /usr/local/www/pfblockerng/pfblockerng.php dc

jwalhous

php /usr/local/www/pfblockerng/pfblockerng.php dc

seems to have fixed the issue

thanks for your help
