It would coincide with a typical fd ulimit of 2048. If the issue is actually too many tcp connections, I can't see why, as both the client and server should close the connection after completion. And, you are running these client connections serially. Maybe try dummying out the database calls. I think Peter is right that it's trying to serialize a database exception and failing. One option would be to handle the db open or query exception yourself in your server and print out the exception (before reraising it). Jim |
