chroot= does not resolve the issue
I have "chroot = login" in my conf
Here is the coredump

Hello
On latest git of dovecot, I get
Apr 24 04:07:36 gjserver dovecot[857958]: imap-login: Panic: file client-common.c: line 293 (client_disconnect): assertion failed: (client->prev == NULL && client->next == NULL)
and login process crash
On 2.3.14, there is no problems
Hope it helps

Hi!
Can you try
service imap-login { chroot= }
and see if you can get a core dump? gdb bt full output would be useful.
