Bump

Did you try with v2.2.21? There are some fixes related to dict.

...

Hi,

We have a dovecot cluster with nfs storage, 2 directors and 3 imap/pop3/lmtp backends.

Redis is used as a dict backend with a dict proxy.

dict { quota = redis:host=127.0.0.1:prefix=user/ }

plugin {

quota = dict:User quota::proxy::quota

}

Redis server is behind haproxy working in tcp mode.

doveadm quota recalc -u user always couses dict process segfault (called from imap backend or director host), otherwise quota is working correctly.

dovecot 2.2.18, redis server 2.8
