There were error(s) - pfctl: DIOCXCOMMIT: Device busy

DaReaLDeviL

Good Morning,

I run in a serious problem with the PFSense, I get about once in a week a crash or hang in my VM PFsense. The time is always the reconnect time after 24 Hours. Now I see the first time a hint in the webinterface without a crash/hang:

05-31-14 05:30:32
[ There were error(s) loading the rules: pfctl: DIOCXCOMMIT: Device busy - The line in question reads [0]: ]

So here are the day before and the day after it from the syslog of the gateway:

So thats what I can give you now. I'm not sure how to find out where the real problem is.
I found a simular problem in another thread https://forum.pfsense.org/index.php?topic=64665
where it is thought to be a operation/rule problem.

Could it be something like the Apinger in a loop or something else? Attached are the Services and Packages.

Please help me out to find a solution for this.

This is another bug on 2.1.3, as I never got this before, and I always use a dedicated machine for pFsense, no VM at all.

Hi Gradius,

thank you for posting your information. Couse I really thought that might be something at my vm. I just deinstalled everything I'm not 100% sure that can couse such trouble. But I still get this error.

Hope that the PFSense Team recognize this and fix it soon.

The only new thing I run now (compared to old versions) is Unbound.

My complete package list:

pfBlocker
snort
squid
Unbound
