I have MPE V 126.96.36.199 running on a cisco MCS server and the memory usage sits at about 99%, with no meetings in progress, is this normal?
If your MPE server is performing reliably, i.e. when you have meetings in progress, and you don't observer performance degradation then it may be just the Linux OS doing its thing - http://kbase.redhat.com/faq/docs/DOC-1139. However, even Linux OS can have memory leaks at times. If you reboot the MPE server, does the memory go down to a lower level of consumption? Growing increase in memory consumption over time could be a memory leak - I checked for MPE version 2.1 release Open Caveats and did find a hit, but would recommend you check with TAC on its appropriateness for your observations - http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsg46516
Hope this helps! Ginger
