For example, if I run 19000 tcp querys at 5-6 querys per second, I end up with about 400 querys failed due to timeouts. Most of the time outs occur in batches, where I see all querys or every other query timeout. Is that simply too many tcp querys for PDNS to handle?

The max-tcp-connection was set to 1000, and figured that would be high
enough, should I increase the limit further?
