Could you create a few 'full thread dumps' if this happens? Usually you can do that using "kill -QUIT <pid>" on Linux, or Ctrl+C on Windows, or jps -l / jstack <pid> (all platforms). I would also need to know more details, such as the database URL. If you are using a TCP connection, maybe the problem is that H2 doesn't use TCP_NODELAY. I just found out today that this may be required on some platforms, I will run some tests and probably add this in the next release.
