On an exchange 5.5 sp4 server running on win2k, the IMC shut down because the IS complained that: "Message processing failed because there is not enough available memory" (EVENT ID 12800).
This was followed by events 4182 and 4102 (ims shutting down due to serious error i.e. 12800) There was one message in the inbound directory of the IMC and it would not start until I removed that message. There was nothing unusual about that message, it was one that BLAT had generated from a backup process I have scheduled. After that restart, it ran for a while and then choked on two other messages. One was another BLAT message and the third was a MPEG movie somebody had mailed in (probably a funny one, I haven't looked at it). All 3 messages were about 10k bytes in length. MS has a knowledgebase article about this problem: (or something very close) http://support.microsoft.com/default.aspx?scid=KB;en-us;q325939 Which says: If the Internet Mail Service receives a malformed inbound Internet message, the Internet Mail Service may log event ID 12800, 4182, 4102, and 1001 error messages in the Application event log, and then stop responding. RESOLUTION A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. The fix is a new store.exe version 5.5.2656.60. I am currently running store.exe 5.5.2654.50 (a post sp4 fix). After zapping those 3 emails, the IMC has been running for about an hour now with no problems (and it has never had a problem before). Does anyone have any insight on this problem? If it happens again I will call MS and request the patch, as it is not available for download.
