========================================================================

I can't relog on share in any way so i need to restart the alfresco service, and after that it's seem the share application working just fine.

It's seem this problem popup after i use the java debug remote of my ide (eclipse, netbeans,ecc).

I use the Alfresco Community 5.2  with the embedded apache tomcat 7.

Someone has encounter already the same problem?

Share did not work because apparently the Repository was unavailable - or at least your proxy server reported it as unavailable.

Without any log information from the Repository (alfresco.log / catalina.out) it will be impossible to determine / guess on a cause.

This problem is confirmed when you are in debug on your own web application under the same tomcat of alfresco.

So the solution is to stop the debug and stop and restart apache tomcat.
