Subject RE: Could not retrieve connection info from pool - DB2

Hmm, everything looks fine.  Did some splunking looking for the 
error message (thanks Eclipse for source jar association!) and 
found it in:


There should be a root cause exception associated with this.
Probably coming from GenericKeyedObjectPool.  Knowing this would
help pinpoint the error location in the commons code.

FWIW, the testOnBorrow option does add a little overhead but 
it also help protect against connections that where closed 
due to network or DB server problems (server restarted or 
server connection timeout reached).

Some other "standard" debugging stuff that you've probably done:

Do you have any other commons-dbcp* or commons-pool* jar files
in the path beside the 1.2* versions in distro?  Could be a bug
in an older version.

Does your app do anything that would not release connections? E.g.,
getting connections from the pool directly and not releasing them
or do you use transactions and don't finish with a commit or
rollback?  Turning on Torque/commons debugging might help identify
such problems.
