MSSQL high CPU usage

georgeanderson — Wed, 04 Dec 2019 22:42:20 GMT

My MSSQL ThingWorx database keeps getting slammed by a query that seems to run very frequently. Here's the query:

SELECT COUNT(*) FROM data_table WHERE entity_id = @P0

I am not sure what is triggering this query, or why. But, data_table is quite large and this query seems to be consuming resources unnecessarily. Does anyone know what triggers this query, and why.

Hi @georgeanderson.

For the benefit of the rest of the community, the fix for this issue was delivered in ThingWorx 8.5.5 released earlier this week.

If you agree with the solution, please mark this post as the Accepted Solution.
