Hi Timo,
Periodic segfaults with doveadm proxy list:
root@director1:~) doveadm proxy list
doveadm(root): Error: LIST failed: Disconnected
Segmentation fault (core dumped)
Sometimes it's just the 'LIST failed' error, other times it's the error with
the segfault. Usually the first attempt to call it works, subsequent attempts
fail.
I've attached a strace log of it in action.
