Cisco Bug: CSCsz22553 - EMS with syslog recipient consumes UDP ports
Feb 22, 2014
- Cisco Unity Servers
Known Affected Releases
Symptom: Unity, Event Monitoring Service (EMS) consumes UDP ports. An EMS Monitored Event can be configured to send notifications to a Recipient which includes a syslog server. Notifications to the syslog server will use a UDP port. EMS does not release this UDP port. Eventually EMS will consume all UDP ports available on the server. Services, such as DNS, will fail when no UDP ports are available for outbound connections. Symptoms include errors connecting to email, kerberos, domain controller, or global catalog servers. Anything dependent on UDP network connections. Stopping the CsEmsSvc service will free the UDP ports. Rebooting the server will also free the UDP ports and get things working for a period of time. Condition: This problem may be seen in EMS v1.3.09 and earlier. This issue is fixed in EMS v1.3.10 and later.
