This could be a potential problem where either CUCM is not sending an ACK for OLC or a similar message or it is being dropped along the way because of some firewall or routing issue. Couple of things that need to be done are
1) Check with the users if there are any dropped calls corresponding to the time stamp of these messages
2) Get the corresponding detailed callmanager traces and filter the h225/h245 messages to check if there are any messages being recieved from the gateway for which an ACK is not being sent by CUCM.
