Hi everyone,

in the log of my alfresco linux installation every thirty seconds alfresco wrote:

14:07:40,971  ERROR [feed.local.LocalFeedGridJob] java.lang.NullPointerException

SOLVED

We had old entries in ALF_ACTIVITY_POST table of Database in inconsistence status.

After deleting them the log's line disappeared.
