JSI Tip 3467. Is there a Workaround for a service which leaks memory?

If you have a service that leaks memory, I have scripted a general purpose workaround, until the author provides a fix.

The MemoryLeak script use the Tlist freeware:

Windows NT 4.0 - 1388 Where are the SP4+ Free Resource Kit Tools?

Windows 2000 - From the Support Tools on the Windows 2000 CD-ROM.Run Tlist manually for the leaky process, and determine your threshold for PeakWorkingSetSize. Then schedule MemoryLeak.bat to run as infrequently as you can afford. The syntax is:

MemoryLeak Process PeakWorkingSetSize ServiceShortName

where:

Process             - Is the process name as displayed by Tlist, generally xxxxxx.exe.PeakWorkingSetSize  - Is the maximum value before the process is stopped and restarted.ServiceShortName    - See tip 3444 How do I find the short name of a service?

NOTE: If when you manually stop this service, it stops other services, you will need to make a custom version of the MemoryLeak script.

MemoryLeak.bat contains:

@echo offsetlocalif {%1}

{} goto syntaxif {%2}

{} goto syntaxif {%3}
