dbcp2 getCinnection wait


We are using dbcp2.x as connection pool library. Have set the property of maxActive as 100. When we run 20 threads in parallel, 2 threads keep waiting for connection and never gets it!!

Is this kind of issues already known as bug in dbcp2?
Kindly share if you have come across with similar issue.

How do you know that 2 threads are waiting for connections?

In the exception trace, for two threads, it is showing that it is waited for dbcp2 classes and than internally it is waiting for lock, and finally timed out and connection not obtained.

As workaround I increased the initial service XD of the connection pool and now it is working.
