Re: Need help identifying the cause for this Cisco IPS 4542 Pls.
You have 2 different issues.
1) It looks like you do have an expired license. Execute "show version" and see what date your license expired. You might try pulling a new license from cisco.com. If your contract has been renewed, you might just need to pull a new license for your renewed contract.
If yout contract has expired, then the contract will need to be renewed before you are able to get a new license.
2) A completely separate issue is that the sensorApp process has terminated. When sensorApp is not running you will get the error message "ct-sensorApp.371 not responding, please check system processes - The connect to the specified Io::ClientPipe failed".
You can again run "show version" and look for the status for Analysis Engine. If the status says Not Running, then sensorApp has terminated.
(NOTE Analysis Engine is the service name that is within the SensorApp process)
You will need to reboot the sensor to get sensorApp restarted.
If this continues to happen ensure that you are running the latest IPS version (to ensure you have the latest code fixes), and if you are on the latest IPS version already then contact the TAC for assistance in determining what sensorApp bug you may be hitting (either known with hopefully a fix being developed, or a new issue which development may need to analyze).
