Hi guys, i've a strange problem between 2 servers. It happened after a changing on our network core routing infrastructure. We've moved to Juniper network and eBGP and iBGP of our server. One of this server is behind a firewall and communicate with another server in another country to sync our emails. Doveadmin replica seems to be fine, but sometimes i get this error message:
dsync-server(aaaaa@bbb.bb): Error: Timeout during state=sync_mails (send=done recv=mails)
It seems like the remote server has troubles to reach our local server but if i do a stupid ping i'm not losing anything.
Maybe is there something am i missing? I thought that it could be related to a MTU problem but i'm not so sure and i've increased MTU on the routers involved in routing process without success. I wa missing that both servers are behind a load balancer wich is in our local DC.
Can you give me some hints? Regards, Paolo

I experience the same errors in my setup. It seems to happen in intervals of "replication_full_sync_interval" for me. Specifically if the "full sync" time in the output of "doveadm replicator status '*'" reaches the full sync interval time for multiple users.

Hi guys, For anyone who have this problem it could be related to routing MTU. In my case I've found that a new router was breaking the mtu so big packet are fragmented and this cause stalled between the replicas. Thank you for your time Paolo
