Description (partial)


RTMT may report that a Cisco Unity Connection server is low on virtual memory and the CuImapSvr is using most of the memory.  Here is an example alert:
%CCM_RTMT-RTMT-2-RTMT-ERROR-ALERT: RTMT Alert Name:LowAvailableVirtualMemory Detail: ... Available virtual memory below 30 Percent. CuImapSvr (3047 MB) uses most of the memory. 

Eventually, the Connection IMAP server will use more then 3000 MB of memory and stop responding to requests.


This issue occurs when there have been lots of TLS/SSL connections into the Connection IMAP Server.
