Hi.
Our scenario: dovecot-2.3.4.1 Two FreeBSD servers, A (master) and B (slave). replication_max_conns = 10 doveadm_port = 60025
All mails are received on server A and replicated to server B.
Sometimes we get these messages on server B:
Feb 18 08:27:35 dsync-server(XX@XX): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:28:00 dsync-server(XZ@XZ): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:33:14 dsync-server(XY@XY): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer Feb 18 08:44:07 dsync-server(XW@XW): Error: client_connection_tcp_free: close((&conn->fd)) @ client-connection-tcp.c:632 failed (fd=15): Connection reset by peer
It happens sometimes (usually early morning) when users are syncing their mailboxes.
Is there a way to debug this and find what is happening?
Thanks for your time.
