How is Apache repaired with CB

[ayberk]

Hi,

I have a problem with Varnish Cache. As seen in the log, the Backend does not work properly. What is your suggestion?

Hello,

The thread was moved from Custombuild sub-forum as Varnish is not supported by Directadmin.

You might need to open a topic on specialized forums which is more general or varnish specific. Of course if somebody here have anything to say regarding the matter it's fine.

Hi Alex,

I wanted to ask you if it's related to Apache. I understand that the problem is not in Varnish but in Apache.
What are you suggesting?

 

[zEitEr]

Check apache logs for errors, that what you should start from.

 

[ayberk]

There is nothing important in the Logs.
But isn't that obvious there is an Apache problem in Varnish's logs?

 

[zEitEr]

I guess if you can define that there is nothing important in Apache logs, then you can find the root cause yourself. Why do you ask us for a help then?
