Hi, during the store of the messages, I find the following doveadm errors:

This problem occurs only with the quota plugin enabled.

Can you help me?

The GDB trace tells me this is most likely a Lucene bug. There is very little Dovecot can mess up at library deinit like that.

Regards,

Stephan.

Best regards
