AlfrescoWeb Script Status 500-Internal Error

Question asked by naveenalfresco on Oct 3, 2011
Latest reply on Nov 16, 2011 by mikeh
We have Alfresco 3.0 (Stable) installed, and everything works fine. We had developed our sites entirely based on the structure of Alfresco share 3.0 but from time to time we get the following error message "AlfrescoWeb Script Status 500-Internal Error” while retrieving data from a space. We have a hunch that alfresco server doesn't respond or shuts itself randomly.It is even slow while fetching data from a space.
