Varnish & phpMyAdmin

[Nagataka]

Running CWP version: 0.9.8.70
Did enable Varnish.
Once trying to start phpMyAdmin from a user or root client, getting the following error:

Error 503 Service Unavailable

Service Unavailable

Guru Meditation:

XID <number>

Varnish cache server

Guess thats not normal behaviour?

I just see that there is another topic about it too:
