You can lsof to check for anything untoward there. This is a known problem with hsqldb AFAIK. We run with hsqldb as in-process.
We also run the IBM 1.4.1 SDK for performance reasons. YMMV but it appears that the IBM and BEA JDK/SDKs have a performance advantage - at least out of the box without any tweaking or special options.
