Feb 25, 2019
- Cisco Unified Communications Manager (CallManager)
Known Affected Releases
Symptom: Memory leak of media processes under CTI redirect error scenario causing sluggish CUCM behavior and unable to process calls after a certain time based on number of times this error scenario is hit. Memory leaked per call is around 21K. Conditions: Issue exists in CUCM 7.x, 8.x, 9.x 10.x. It is a remote scenario which causes a process leak for certain conditions where the redirection fails due to some error while the caller was originally the called side of a call. One such scenario : A calls B. B answers. CTI Redirects A to C. B and C are connected. ( note that B is Side A of the call now ) CTI tries to redirect C to D but this redirection fails due to some configuration error (dial invalid DN) Even though; redirection restore should happen (B and C should be connected); this does not happen and the media is not cleared. This causes memory leak of the media processes. If redirect is successful , we will not hit this issue.
