strange 503 service unavailable

#1
I can see my main Magento site, can access a wordpress site within the folders of Magento, but can't access the xcache-admin site.

Can anyone shed any light?

I see this error in the server logs:

I disabled xCache as it was causing this 503 mess. I don't know what it was.

I found this in the stderror.log file..

Don't know if that points to anything?
