Recovering CUE Module from an Errant State

I was getting ready to start my Cisco Unity Express lab and ran into this issue where the CUE module was stuck in errant state.

Once I sessioned into the CUE module this is what I saw:

BR2-RTR#service-module service-Engine 1/0 session

Trying 10.10.202.1, 2066 ... Open

EXCEPTION: /sw/info/ps: -5: out of memory for event sources

- waited 15400 seconds...

This out of memory message is caused by the bug CSCeg66388 which means that the Cisco Unity Express module has tried to establish connection with the IOS router multiple times and was not successful.

You can go ahead and reset the module to fix this issue:

BR2-RTR#service-module service-Engine 1/0 reset
Use reset only to recover from shutdown or failed state
Warning: May lose data on the the NVRAM, nonvolatile file system or unsaved configuration!
Do you want to reset?[confirm]
Trying to reload Service Module Service-Engine1/0.
Mar 4 01:15:49.835: %LINEPROTO-5-UPDOWN: Line protocol on Interface Service-Engine1/0, changed state to down
Mar 4 01:15:59.835: %LINEPROTO-5-UPDOWN: Line protocol on Interface Service-Engine1/0, changed state to up
Mar 4 01:16:00.839: %OSPF-4-NO_IPADDRESS_ON_INT: No IP address for interface Service-Engine1/0

This should take care of the issue but if you were reusing an existing module that had configuration and wanted to wipe it clean then proceed with the following command:

se-10-41-1-16# offline
!!!WARNING!!!: If you are going offline to do a backup, it is recommended
that you save the current running configuration using the 'write' command,
prior to going to the offline state.
Are you sure you want to go offline[n]? : y
se-10-41-1-16(offline)# restore factory default
!!!WARNING!!!: This operation will cause all configuration and data
on the system to be erased. This operation is not reversible.
Do you wish to continue[n]? : y
Restoring the system. Please wait .....done
System will be restored to factory default when it reloads.
Press any key to reload:

I am glad I ran into this issue during my prep because this is something you don't want to see for the first time in the lab. I hope this was helpful to you!
