Hi Marc,
try to set the option:
# action to take when the pool is exhausted {grow|block|fail}
db.pool.default.whenExhaustedAction=block
from "block" to "grow".
I assume there is some potential deadlock - code in commons-dbpc when
that option is set to "block".
also try to turn on eviction by commenting in the test query in that file.
Kind Regards,
Achim.
