Doveadm error during store - segfault clucene

Dovecot mailing list


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

2019-10-02 09:22:19 auth: Debug: ldap([hidden email]): result: mailMessageStore=1/1/2/0/8/7/2/1120872_91093 mailQuota=52428800; mailQuota,mailMessageStore unused

2019-10-02 09:22:19 auth: Debug: master in: USER    1    [hidden email]    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([hidden email]): Performing userdb lookup

This problem occurs only with the quota plugin enabled.

Can you help me?

Best regards

Domenico
