I receive the above error via email shortly before pfsense crashes. Upon crash, all LAN/WAN is inaccessable, and SSH and console are also unresponsive. Pfsense can only be recovered by hard reset.

I am currently running 2.4.4-RELEASE-p2 and pfBlockerNG-devel 2.2.5_22. However, this error has happened every couple weeks for a few months, and would have happened with earlier versions of pfblockerNG-devel as well.

I haven't been able to find any similar situations through searching the webs. Any help and suggestions would be greatly appreciated!

Do you have enough free hard drive space in this box? Memory? Do you have any other errors in the pfSense system.log?

Hi BBcan177, I appreciate the reply, I have been a big fan of your work for some time.

I have plenty of hard drive space (6% of 12GiB) and memory (25% of 4GiB). Please see dashboard screenshot.

I don't see other obviously related errors in the log, I do have these, but I'm not sure if they are related.

I am still having this issue every 2-3 weeks. It is very frustrating as it can only be recovered by manual hard reset. This is the most recent notification I received today:

Any assistance would be greatly appreciated!

@Risfold
I have made a few revisions to the code to address this issue.
Changes here:
https://gist.github.com/BBcan177/fd7aa11babc3280ab593cacb86a60257/revisions

To test, please run the following command to download this patched file:

fetch -o /usr/local/pkg/pfblockerng/pfblockerng.inc "https://gist.githubusercontent.com/BBcan177/fd7aa11babc3280ab593cacb86a60257/raw"

Follow that with a restart of the "pfb_dnsbl" service.

Let me know if the error repeats. Thanks!

Risfold

@BBcan177 thank you very much for looking at this. I will implement the patched file and report back if the error recurs. I'll also respond in 3-4 weeks if there is still no issue.
