I am seeing the same as Michael Grimm also on FreeBSD-11. You’ll also notice in doveadm replicator status ‘*’ that the failed flag is raised for those users and that there are processes just hanging forever when those logs start to appear: <user> 45949 0.0 0.0 47888 13276 - I 20:20 0:00.10 doveadm-server: [<user> Verwijderde items send:mail_requests recv:changes] (doveadm-server) <user2> 45964 0.0 0.0 49860 11608 - I 20:20 0:00.05 doveadm-server: [IP6 <user2> INBOX import:1/3] (doveadm-server) <user3> 45965 0.0 0.1 58256 19820 - I 20:20 0:00.11 doveadm-server: [IP6 <user3> INBOX import:16/18] (doveadm-server) <user4> 46480 0.0 0.0 53536 16288 - I 20:22 0:00.08 doveadm-server: [IP6 <user4> INBOX import:4/6] (doveadm-server) <user5> 46745 0.0 0.0 51496 14184 - I 20:22 0:00.07 doveadm-server: [IP6 <user5> INBOX import:5/6] (doveadm-server) I also reverted to 2.2.35 because I started to get complaints from my users that mail was missing.
