Hi, guys,

     we have Alfresco 3.0 (Stable 1526) installed, and everything in Web Client (http://locallost:8080/alfresco) works fine. But in Alfresco Share, we get the following error message "HTTP Status 500 " from time to time, especially after creating a new space and doing something new in that space. Does anybody here experience the same problem as we have? thanks

Have you looked in your log files for more information, catalina.out (in tomcat/logs) and of course alfresco.log would be a good place to start.

We've had some problems with HTTP status 500 and exception reports like that and I believe that the root of our problems was the fact that Alfresco creates more file connections than the underlying operating system allows. That could be something to look into, in that case you should find error messages stating "Too many open files" in catalina.out.
