SYMPTOMS
The message transfer agent (MTA) for Exchange Server version 5.5, 5.5 Service Pack 1 (SP1), 5.5 Service Pack 2 (SP2), and 5.5 Service Pack 3 (SP3) may stop unexpectedly if you restart it after an abnormal shutdown. The MTA logs an event 9405 in the application event log that is similar to the following:

An unexpected error has occurred which may cause the MTA to terminate.

Error: Access violation (0xc0000005) at Address 0x42572e reading from 0x104. [BASE DISP:FANOUT 10] (16)

Note that the address for the access violation may differ slightly depending on the version of the MTA. This issue is encountered at address 0x42572e for the Exchange Server 5.5 SP2 MTA. Servers that are configured to generate User.dmp files and Drwtsn32.log files using the Drwtsn32.exe program may produce a call stack similar to the following for the issue thread: FramePtr ReturnAd Param#1 Param#2  Param#3  Function Name 03dfff28 004251fa 0044a10b 006927c8 01e68910 emsmta!otpmrfo [omap] 03dfff48 00443a8d 0044a10b 01ea4fa0 01be0014 emsmta!otpmmai2 [omap] 03dfff8c 0044a13a 01be0014 1004f86c 0000000b emsmta!otpmmain_897nThread::HrGetListenPort_26ad_81170ad [omap] 03dfffb8 77f04f3e 0000000b 01be0014 1004f86c emsmta!sbpiwbep [omap] 03dfffec 00000000 00000000 00000000 00000000 kernel32!lstrcmpiW 00000000 00000000 00000000 00000000 00000000 emsmta!OMP_D_MH_EE_GENERAL_TEXT
