[Pound Mailing List] syslog error messages

In syslog we are seeing the following types of errors:


1) Dec  9 14:27:41 ip-172-31-22-40 pound: (7fe7401fa700) error read from 98.160.103.132: Connection timed out

Q - Is this caused by the client dropping the connection (ie browser shutdown) or is this an issue between pound and the backend servers?


2) Dec  9 14:27:48 ip-172-31-22-40 pound: (7fe73ee6d700) error copy chunk cont: Broken pipe

Q - Is this an error between pound and the backend servers?


Any help on understanding these errors would be helpful.
