Could you give some more details?

Interesting information would be:
1) configured Resource Type of the pool
2) Datasource Classname used
3) Do they connect to the same or different databases
4) Do they connect to the same or different servers
5) Full Java version
6) Jaybird version (including JDK version of the drivers!)

Any other interesting information (how do the applications use their
connections, how do they acquire them, what is the load)

I've tried two (almost identical) simple (web)applications on Glassfish
2.1 that acquire a connection and query a table, but I wasn't able to
reproduce this (not even under (some) load).
