[Dovecot] Segfault when using multiple servers

[Marc Maurer]

Should it be possible to run multiple dovecot servers on the same
mailboxes (Maildir in my case)? I've a setup where 2 dovecot 0.99.13
servers write to the same mailboxes, which dovecot apparently does not
like too much.

Example (using imap):

- Login with mail client on server1
- Login with webmail on server2
- Delete a mail using webmail on server2
- Hit send/receive in the mail client

Result: server1 segfaults.

Is such a setup, which is basically a loadbalancing setup, allowed at
all by dovecot?

Cheers,
