Hi Steve,
We definitely need more details:
-How was this analysis done, what tool was used ?
-Over what period of time this usage was measured, from screenshot appears around 10-11 hours but pls. confirm ?
-Did this cause any performance issues with the application itself ?
As you indicated this thread is part of the Smart Instrumentation feature in Agent and by itself thread is not doing a lot of processing, simply updating system time though runs very frequently(read quickly). As such it normally shouldn't have any impact to application performance or block any processing.
Regards,
Kulbir.
