Failed to read JSON response from metadata service

[mike54]

Hi,

I have my installation running for a small developer team. We have around 10 users.
More or less Share site functions correctly. Users are complaining from time to time that they had some problems using it.

As I couldn't replicate problems I have searched through logs an one of the common WARNings is:

0:54:16,656 WARN  [org.alfresco.web.config.forms.NodeTypeEvaluator] Failed to read JSON response from metadata service.
org.json.JSONException: A JSONObject text must begin with '{' at character 2 of ‍‍

—————
Alfresco 3.2
Centos 5 + Tomcat + Apache
MySQL

We're suffering from the same problems with 3.4.b on Windows 2008 r2.
But because we use a reverse proxy in front of Alfresco, the error is a bit different and mentions AJP-8009:

I'm curious if this is a bug, or if this is "normal" behaviour.
Can't really say what the effects are of this WARN as well (but don't like things like these to occur in Logfiles)
