the peer has terminated the connection in which case syslog-ng automatically reconnects. these lines should contain more information :(

anyway, you can find out what happens by tcpdumping the network interface and looking for RST packets.

getting these errors at a rate of several per second but I can't figure out what is causing them:

we have one network destination which is a tcp connection and which appears to be fine.  No errors on the other end and stats show now dropped packets.
