Error on varnish start after update

Hi team

I have a nginx+varnish+apache+php-fpm server working fine up today. After the last CWP update and system update, varnish has gone mad. Varnish can't start at all so all accounts using varnish stop working.

This is the only log file i found:

Code: [Select]

No varnish, nginx or apache parameters have been touched, only the configuration was applied to the domain of a new account in the menu "Webservers Domain Conf".

Once the problems started, I used the "Select WebServer" option to try to solve it. Also tried removing varnish and installing it again. I have also reinstalled the entire CWP server from scratch and still the same thing happens. I can't find any reference to this error. Any ideas?

Regards
