You need to tell us exactly what you do to use those threads so we can reproduce. Btw: why do you have that c3p0 config?

We are not doing anything special - several datasources are connected to the Metabase (Postgres, Oracle), from which we take information for the dashboards that users work with.

idleConnectionTestPeriod was needed because network devices between the DBMS and Metabase sometimes unexpectedly broke network connections; maxIdleTime and unreturnedConnectionTimeout were added in an attempt to help with increasing number of threads.

I also have dumps for different days - you can see the dynamics of increasing number of HelperThreads (Samurai, for example, can visualize the difference between several dumps):
metabase-20240427.dmp
metabase-20240501.dmp
metabase-20240503.dmp
