Pfr_unroute_kentry delete failed

[Heimire]

Pfsense 2.1.5

We have 2 pfsense boxes using CARP.
One wan gateway.

The slave box will freeze up and the error: pfr_unroute_kentry delete failed is on the console.

I did search for this but I am not sure how to fix it, it’s a bit unclear to me exactly whats the problem.
It seems that one of the suggestions was to turn off the gateway monitoring?
But honestly I am not sure I understand exactly.

Does someone has any info they could share so we can get this working?

[Heimire]

Nobody?

You running BGP or OSPF on there? It's an unusual circumstance, but that's the only scenario I can think of where that can happen. It's something that's fixed in the base OS in 2.2.

[Heimire]

Not running either BGP or OSPF.

It has happened 3 times in the last month and a half I think.

This is on a test system with low load, no more then 5mb of internet traffic going to 2 servers.
Xeon L5335 cpu and 8gb of memory.

Any large tables (aliases/pfblocker) on there?

[Heimire]

We have pfblocker on there.
We only had pfblocker with the top spam countries listed and no other lists when it failed the first time.

We have the following packages:
Arpwatch
Autoconfigbackup
bandwidthd
Snort
Postfix
Mail scanner
nrpe v2
openvpn client export utility
pfblocker

[cmb]

pfblocker is definitely the cause in that circumstance. I believe that to be fixed already in 2.2.

Thank you very much for taking the time to respond.

Will disable pfblocker and see how it goes.
