[Pdns-users] TCP nameserver had error, cycling backend

[Eugene Pefti]

Hi folks,

What could this error message mean?

Jun  5 21:28:53 ns2 pdns[5778]: TCP nameserver had error, cycling backend:
Reading data: Connection reset by peer

They are numerous indeed. I believe they affect the overall performance.
And why would this stats show up in the log:

Jun  5 21:44:33 ns2 pdns_recursor[5200]: stats: 181355 questions, 86152
cache entries, 363 negative entries, 15% cache hits         
Jun  5 21:44:33 ns2 pdns_recursor[5200]: stats: throttle map: 41, ns speeds:
135                                                    
Jun  5 21:44:33 ns2 pdns_recursor[5200]: stats: outpacket/query ratio 166%,
1% throttled, 0 no-delegation drops                     
Jun  5 21:44:33 ns2 pdns_recursor[5200]: stats: 353 outgoing tcp
connections, 4 queries running, 18833 outgoing timeouts

Can these recursor erros be correlated with pdns errors?

And finally, can somebody interpret this even more numerous message:
Exception: unknown escape sequence
