Cisco 4235 IPS v6

Hi guys,

one of our sensors is currently having problems not wanting to scan any traffic. when we reload the sensor we get the follow error

"errorMessage: SignatureDB: TcpRootNode non-zero refcount (1st pass) - exit destructor name=errUnclassified" and then the sensor justs default into bypass mode again.

does anyone have an idea of what happened and what do I need to do to fix this.

thanks.

Will.

Re: Cisco 4235 IPS v6

The error indicates that the internal data structures have not completely cleaned themselves up. But this is not a big issue as it may happen during a normal shutdown. Check the memory and CPU load of the device. You may need to install more memory on the sensor.
