The Microsoft Exchange Service Host service (Microsoft.Exchange.ServiceHost.exe) on a Microsoft Exchange Server 2010 server crashes intermittently. Additionally, the following event is logged in the Application log:
Log Name: Application
Source: MSExchange Common
Event ID: 4999
Task Category: General
Watson report about to be sent for process id: <process ID>, with parameters: E12, <build type>, <application version>, M.Exchange.ServiceHost, M.Exchange.Diagnostics, M.E.D.ExEventLog.LogEvent, System.ArgumentException, <callstackHash>, <assembly version>.
This issue occurs because the EventLog.WriteEvent
method throws an ArgumentException exception when an event text is larger than 32,766 characters.
To resolve this issue, install the following update rollup:
Description of Update Rollup 3 for Exchange Server 2010 Service Pack 1
