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?
Depending on how you are doing this, you may be hitting the max-tcp-connections default, which is 10. If you want to do lots of TCP queries, I suggest increasing max-tcp-connections a lot.
Kind regards,
