Any idea what is causing "Borrow prepareStatement from pool failed"?

The only possible cause coming to mind right now is a pool that is exhausted
- meaning there are long-running DB operations.  If that's the case, then
tuning the DB, moving to another store, or possible tuning the pooling
settings for JDBC may help.

It is also possible here that such a scenario will occur when there are too
many messages backing up in the broker due to slow consumption.  If so, then
it is critical to eliminate the slow consumption.
