Hi Shawn, Check the Catalina home and see if your tomcat set up Is pointed to the correct path. You can check that from the registry as well to make sure the service is not pointed to another tomcat which might have these parameters setup.
The registry path is HKEY_LOCAL_MACHINE --> software-->wow6432node ---> apache software foundation. Else you might want to check if the same is a problem with DBCP pool as well . As from the details shared looks like you are using jdbc pool.

Hi Shawn, No, I don't think that maxActive means that it's defining the maximum number of connections for the pool, I think it's strictly referring to the "[ .. ] maximum number of *active connections* that can be allocated from this pool at the same time. [ .. ]" (emphasis mine on active connections) Here is the doc that I've been referring to - sorry for not linking it earlier: https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftomcat.apache.org%2Ftomcat-9.0-doc%2Fjdbc-pool.html&data=04%7C01%7Cjalaj.asher%40eclinicalworks.com%7C3f5dd36a4b0d458695d908d8a1371f11%7C7ce747e48f6d4e0697efa9b76a063808%7C1%7C0%7C637436605411941490%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=bPYOMGVa0dYi0ASx%2BuQ5pTdlzpuOKird7pAVi%2FjHQVs%3D&reserved=0 On those other Tomcat servers is there a initialSize defined?

On other tomcat servers I have, maxActive is set to 50 and I verified im jmx that there are 50 max connections on the connection pool. Here though I checked jmx, sure enough, its max connections is 8.

Default value is 10 maxActive (int) The maximum number of active connections that can be allocated from this pool at the same time. The default value is 100 It would make sense that 8 connections would be 80% utilized. I would try replacing maxActive with initialSize and seeing how that works for you.
