TIPS:Recovering a Cisco Unity Express Module from an Errant State

When candidates who are taking the Cisco CCIE® Voice lab exam initiate the Cisco Unity Express module,
they occasionally find it stuck in an errant state, where it continuously displays this message across the console:
EXCEPTION: /sw/info/ps: -5: out of memory for event sources
EXCEPTION: /sw/info/ps: -5: out of memory for event sources
Waiting for IOS to register IP address.
- waited 12490 seconds...
WARNING:: IOS communication appears delayed!
WARNING::
WARNING:: Please verify the Service Engine IP Address
WARNING:: and Default Gateway are configured correctly
WARNING:: on the service engine interface in IOS.
EXCEPTION: /sw/info/ps: -5: out of memory for event sources
EXCEPTION: /sw/info/ps: -5: out of memory for event sources
EXCEPTION: /sw/info/ps: -5: out of memory for event sources
This “out of memory” message is caused by the defect CSCeg66388. In this scenario, the Cisco Unity Express module is stuck after repeated failed attempts to establish IP connectivity with the Cisco IOS router.
The solution is to reset the Cisco Unity Express module to recover it from this faulty state. Any of these three methods will solve the problem.
1. Use “--6 x” to return to the Cisco CallManager Express enable mode. Then
reset the Cisco Unity Express module using this command:
CCME# service-module service-Engine 1/0 reset
2. Launch another Telnet session to Cisco CallManager Express and execute the command-
line interface (CLI) above to reset the Cisco Unity Express module.
3. “wr mem” and reload the router. This method is a little dramatic, but it does work.
Here are some additional commands that can be used to manage or retrieve information about the Cisco Unity Express module from the router CLI:
CCME# service-module service-Engine 1/0 ?
password-reset Password reset of Service Module
reload Reload service module
reset Hardware reset of Service Module
session Service module session
shutdown Shutdown service module
status Service Module Information
When encountering unexpected problems, such as this errant state defect, it is important to stay calm and to use common sense and experience to resolve them. Good luck pursuing the CCIE Voice Certification.
