php fatal error in rescue_core_module

Hi,

I have a multiserver setup with 3 servers (web, mail, database)
Installed ispconfig version is 3.0.5.4p1

On the database server I have this error in /var/log/ispconfig/cron.log:

And the /var/log/ispconfig/ispconfig.log tells me:

... which isn't true. I can connect to the local mysql, and I can connect to the web-server (main ispconfig installation) server using port 3306.

The other servers logs are empty.
Any ideas?

 

From within the database server console:
netstat tells that it's listening on *.*
But telnet localhost 3306 doesn't connect.

> netstat -tap | grep mysql

tcp 0 0 *:mysql *:* LISTEN 15221/mysqld
tcp 0 0 dbdomain.tld:mysql webdomain.tld:55293 VERBUNDEN 15221/mysqld
tcp 0 0 dbdomain.tld:37181 webdomain.tld:mysql TIME_WAIT -
tcp 0 0 dbdomain.tld:37167 webdomain.tld:mysql VERBUNDEN 8547/php
tcp 0 0 dbdomain.tld:mysql webdomain.tld:54584 VERBUNDEN 15221/mysqld

dbdomain = domain of my database server
webdomain = domain of my webserver (ispconfig main installation)


hosts file is standard, localhost entries are:
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback

But nevertheless, netstat shows that the webserver is connected to the database server.
So the ispconfig check of the database seems to check localhost (ipv6)

 

Ok no idea why but telnet tries

and so does ispconfig. After unblocking ipv6 in iptables, it works now



Nevertheless, till can you tell me if there's any other cron besides crontab -e

as the error was repeated every 22 minutes:

Or maybe the database check is made only every n-th run of the cronjob?
