The error printout is maybe a bit overly dramatic, perhaps this specific error, since it only indicates another host on the internet closed the connection, should not be printed at low verbosity. But this does not seem to explain the tcp issues you say you have. What is the observed problem again? What queries are giving resolution problems and timeouts - are you sure they even use tcp - and can you do a unbound-control dump_requestlist if the query times out (it may still be in the requestlist and we can then see what is going on) and unbound-control lookup (that says what unbound would probably do if it were in the requestlist). And possibly enable a higher verbosity (which you can do very easily without a restart; unbound-control verbosity 4; (wait) ; unbound-control verbosity 1 ) but you would want to actually catch the offending action in the verbosity which may get tricky (higher verbosity can slow down the server significantly and produce Gbs of logs so on high traffic servers you really cannot leave it on). > Could this be linked to the fact I compiled Unbound 1.4.6 with ldns > 1.6.4 (saying that because Paul Wouters opened a thread about possible > dangerous linking when building RPM - something you've just fixed in > 1.4.7). No, unbound mostly uses ldns to read-write DNS to ascii, tests and other stuff, but not for TCP.
