IMAP clients often start IDLE command while they aren't doing anything.
Server is then free to send any mailbox changes to the client. The above simply
means that client had started IDLE command and the TCP connection got
disconnected (maybe intentionally by the client).

The client didn't issue IDLE command and didn't send anything at all for
30 minutes. Dovecot disconnected the client since it wasn't doing anything.

Number of bytes in the TCP connection, input/output.
