Hi.
When I try to log in the Roundcube Webmail, always gives kernel segfault error 4 in the libmysqlclient.so library. Here is the errors in Syslog:

Nov 24 16:09:56 Mail-ovh RoundCube: <k9aon6QP> Failed login for xxx@example.com.br from 201.92.219.184 In session k9aon6qpc6umnlbv (error: 1)

Any suggestions on how to solve this problem?

Thank you in advance.

Forgot to say that all other aplications runs fine, like phpmyadmin and postfixadmin.

This isn't going to be a problem in Roundcube no SQL query should ever cause the sql client to segfault. Your problem is either with the sql client or server or possibly how there packaged for your os. The one thing I noticed is that you said you're using mariadb but the segfault is coming from libmysqlclient so you may need to switch to libmariadbclient. That said your likely going to get better support asking on a form either for your OS or for mariadb since that is where the problem is coming from.

Hi SKaero.
You are write.
Solved!
The problem was a password mismach on dovecot acces to mariadb.

Corrected the files:
dovecot-last-login.conf
dovecot-share-folder.conf
dovecot-used-quota.conf

Now roundcube is working!!

Thank you and sorry for the noise.
