[MySQL & i-MSCP] Error after upgrade to 1.1.17

Hi!

I upgraded i-MSCP to 1.1.17 this morning (08:40). I did do a quick test run this morning too, on a seperate server, but no errors there (yet).
Both installations went fine, no errors found (in log files/during installation) what so ever.

After about 3 hours I received some exceptions via e-mail, I pasted them on pastebin:
1. http://pastebin.com/Gx4w3b9x
2. http://pastebin.com/CKJZMyg6
There are about 4 more identical e-mails.

Some meta-information
The upgrade was from 1.1.16 to 1.1.17.

Checked the setup log, no abnormal exit codes or error codes found in it, ended nicely with http://pastebin.com/GtVD4bg3

The websites do work, the control panel seems to work too (no visible errors as of this moment), it's just those emails with strange exceptions.

Hi Nuxwin,

Debian 7, wheezy (that's 4.4.5)
SQL server is "Server version: 5.5.40-0+wheezy1 (Debian)"
SQL grepped from syslog: http://pastebin.com/CFJH9bTX
/etc/mysql/my.cnf: http://pastebin.com/d897HMBa
In the conf.d only these files, and a .keepme file (empty).
/etc/mysql/conf.d/imscp.cnf: http://pastebin.com/ms4Cbhet
/etc/mysql/conf.d/mysqld_safe_syslog.cnf: http://pastebin.com/xmsTNuLQ

Sure

The strange thing is, that the CP does work and the websites do too, maybe the socket for the cli or py is wrong?

About that socket, it does exsist:

# grep "DATABASE_HOST" /etc/imscp/imscp.conf
DATABASE_HOST = localhost

Sent you the hosts file in private.

Hi Nuxwin,

As of a few minutes ago, I still receive the identical e-mails.
The panel does work indeed, but the e-mails are still being sent.
