Ah, I hadn't connected that thread with this. After rereading that
thread with the information from this thread in mind, I think what
you describe on the other thread could well be the "thundering herd"
problem. Some form of connection pooling could well help.
BTW, I hope you've updated to the latest 8.3.x by now. If not, you
should expedite that.
