SYMPTOMS
Exchange Server 5.5 may stop responding (crash) on the PUSH_NOTIFY function. The stack trace is similar to the following:

FramePtr RetAddr   Param1   Param2   Param3   Function Name 0156f6d0 004e7348  00000000 0156f718 0156f710 STORE!PUSH_NOTIFY::PushToClient+0xb0 0156ff20 004e999c  00000000 0156f718 0156f710 STORE!ScanForOutstandingNotifications+0x104 0156ff70 77e6cbe8  00000000 0156f718 0156f710 STORE!EcProcessTask+0x1b4 0156ffd0 00000000  00000000 0156f718 0156f710 KERNEL32!BaseThreadStart+0x64



CAUSE
This problem can occur because the PUSH_NOTIFY class needs to be reference counted, but it is not. So the PUSH_NOTIFY class is rarely freed, even though it is referenced, which results in a crash.

After the databases have been upgraded, you can restore an earlier version of the Store.exe file on the server, but only if it is version 5.5.2652.68 or later. If you restore a Store.exe file earlier than version 5.5.2652.68 after the database has been upgraded, you are no longer able to start the information store.
