When you gain access to the EventLogEntry class in the System.Diagnostics namespace, a leak in Thread Local Storage (TLS) may occur. This leak causes Event ID 4199 event entries in the Application event log. The event description appears similar to the following:
Event Type: ErrorEvent Source: COM+Event Category: ExecutiveEvent ID: 4199Date: 4/11/2003Time: 11:42:07 AMUser: N/AComputer: <Computer Name>Description:The COM+ Services DLL (comsvcs.dll) was unable to load because allocation of thread local storage failed. Process Name: ReadEventLog.exeError Code = 0x80070008 : Not enough storage is available to process this command.COM+ Services Internals Information:File: .\comsvcs.cpp, Line: 289
A combination of two problems causes this issue:
The EventLogEntry class incorrectly loads the event log entry message file DLL as an executable module instead of as a data file.
A TLS index leak occurs when loadlibrary is called against the DLL (Comsvcs.dll, in this case). This Comsvcs.dll leak occurs only on computers running Microsoft Windows 2000. A fix for this problem is available in COM+ Rollup 27.
Note Other DLLs may also experience the same TLS index leak behavior (the small computer system interface (SCSI) device driver for Tivoli Storage Manager (Adsmscsi.sys) is a known file that experiences this behavior). When a different DLL experiences this problem, the same 4199 event log entry appears. However, the entry has a different Event Source and Description.
The following hotfix is for the System.Diagnostics.EventLogEntry class in the .NET Framework.
