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

2019-10-02 09:22:19 auth: Debug: ldap(test.pop@test.xxx.it,10.11.47.60<mailto:test.pop@test.xxx.it,10.11.47.60>): result: mailMessageStore=1/1/2/0/8/7/2/1120872_91093 mailQuota=52428800; mailQuota,mailMessageStore unused 2019-10-02 09:22:19 auth: Debug: ldap(test.pop@test.xxx.it,10.11.47.60<mailto:test.pop@test.xxx.it,10.11.47.60>): Finished userdb lookup 2019-10-02 09:22:19 auth: Debug: userdb out: USER 1 test.pop@test.xxx.it<mailto:test.pop@test.xxx.it> home=/store/mailbox/mailbox_test/1/1/2/0/8/7/2/1120872_91093 quota_rule=*:bytes=52428800 mail_plugins+= 2019-10-02 09:22:19 doveadm(test.pop@test.xxx.it<mailto:test.pop@test.xxx.it>)<180667><MO3BGytQlF27wQIAxhuf8Q>: Fatal: master: service(doveadm): child 180667 killed with signal 11 (core dumped) 2019-10-02 09:22:19 auth: Debug: master in: USER 1 test.pop@test.xxx.it<mailto:test.pop@test.xxx.it> service=doveadm lip=192.160.10.100 lport=924 rip=10.11.47.60 rport=56515 2019-10-02 09:22:19 auth: Debug: ldap(test.pop@test.xxx.it,10.11.47.60<mailto:test.pop@test.xxx.it,10.11.47.60>): Performing userdb lookup

This problem occurs only with the quota plugin enabled.

Can you help me?

Best regards
