Hi,
I am using CWP, which server is Nginx+Apache+Varnish but I often meet followed error:
Error 503 Service Unavailable
Service Unavailable
Guru Meditation:
XID: 2116764197
Varnish cache server
After I refesh the page, it will be ok, but I think it's a problem, so if there is anybody could give me some idea to fix that, please?
Thanks in advance,

firstly you should check your server logs and based on that you can search for issues with your web servers.
it could be apache limits, mod security or something else.

Hi dear Administrator,
I checked /usr/local/apache/logs/error_log and not find the related error about varnish server.
I have to point out that when we meet this error, I just refresh the page then we can go ahead. But we have met this error sever times, so we hope find some way to fix that.
So could you give us some apache limits and mod security tips, please?
Thanks in advance,
Xiaotao Cao

you need to track your server visitors and check performances to optimize the server, if that's the issue.
However, you need to check this issue with experienced system admin or our managed support for more detailed check of your server.

I wonder if your one time support could fix this Error 503 service and solve the Drupal can't create scaled thumbnail image automaticly and do some performance optimize for our server? If you can, I like to use the one time support.

Hello.
Yes, you can contact with the support service.
But don't forget to tell us how we can reproduce the issue.
