Hi.
When I try to log in the Runcube 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.

Is it a IDN? (Punycode)

How much RAM do you have?

Hi Cthulhu.

I think memory is not the problem, the server has 16Gb of ram. iRedadmin works smoothly just like phpmyadmin. The only problem is with the roundcube.

Either a sloppy coding in the actual sql library, or a problem with roundcube

can you make a 2nd installation with 1.5.6 LTS
https://roundcube.net/download/

use the installer script, then you can just change the softlink to point to the different installations without tinkering with the original installation

Can I install SOGO in a easy way? Becose I deselected Sogo in the initial iRedmail install.

Re: Kernel SEGFALT when login on roundcube (limysqlclient.so.21.2.35)

Thanks for your assistance, I tried reinstalling mariadb with the following command:
apt install --reinstall mariadb-server php-mariadb-mysql-kbs mariadb-common mariadb-client libmariadb3

But the kernel error persists.

I will do some more tests this week. If I find a solution I'll post it here.
Thanks for trying to help me!

Please try to upgrade all binary packages on your server with "apt update && apt upgrade", then reboot server.

Did you ever install packages from third-party apt repositories? especially mysql related packages.

SOLVED!

Password for vmailadmin mismach on dovecot.
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.
