I have a SharePoint Foundation 2010 environment where the SPTraceV4 service keeps being disabled. I narrowed down the issue to when the "Health Analysis Job (Hourly, Microsoft SharePoint Foundation Timer, All Servers) runs. There are two other Health Analysis Jobs here, but neither one of them causes the SPTraceV4 service to stop and be disabled.
When the service is running, diagnostic logging works fine. When this timer job runs, however, it fails.
I also have a test environment, which uses the same managed account for this service. It is not failing, so it is not password related.
This is a multi-tier SharePoint Foundation 2010 environment.
Help is defintely appreciated here!
