Cisco 2951 - unknown Error in log

[Chris9811]

Hello,

since two weeks i have a little problem with my Cisco 2951.

My problem is, that i get the following error from my Cisco router every 10 seconds:

*Mar 17 12:14:19.728: %SYS-2-BLOCKHUNG: Task hung with blocking disabled, value = 0x1. -Process= "Inspect process", ipl= 0, pid= 321
-Traceback= 5C39364z 4F4F3D8z 404CC10z ADCF40Cz 4F687ACz 4F4F6DCz

*Mar 17 12:16:48.700: %SYS-2-BLOCKHUNG: Task hung with blocking disabled, value = 0x1. -Process= "Inspect process", ipl= 0, pid= 321

and i dont know what this error means? I hope anyone can help me out.

Traceback always means an IOS bug.

Ok.

Thank you very much for the fast answer!

That means i have to update my IOS?

I have been getting a similar issue since 15.6(2)T and I have to keep reverting to 15.6(1)T2.  I get the follwing tracebacks continually:

It is very evident to users when SIP calls are in place as the traffic is interupted.

I noticed 15.6(1)T3 is available so I will try this and retest to see if its still in this release.  EDIT:  Installed 15.6(1)T3 and this doesn't exhibit this behaviour.  15.6(2)Tx, 15.6(3)Mx and 15.7(3)M all have this issue.

We are also facing the same issue.

Even after IOS upgraded to latest stable code still issue persists.
