    Problem with connecting to MWG through GUI..

      Hello..

       

      i have a MWG 4500 with version 7.1

       

      i don't know why this problem happened suddenly. when i try to connect to the MWG through any browser, i get an error message saying:

       

       

      MWG GUI error.png

      i applied the command (/etc/init.d/mwg restart), and restart all the system but still facing the same problem.

      please give me you advices ASAP..

       

      regards.

          Hello,

           

          did you try to clear the browser/java caches?

           

          Best,

            thanks Andre.

             

            i cleared it and i tried to reach the MWG from three workstations but it didn't connect..

             

            regards.

              Hi,

              what was the last change on MWG before this error message was shown??

              Are you using a MWG config cluster or is it a single node?

              cheers,

              Thorsten

                Hello,

                 

                sorry to hear, usually that helps. If it doesn´t work from multiple workstations it is most likely something on the MWG side. Do you still have access via SSH?

                 

                You may want to have a look into

                 

                /opt/mwg/log/mwg-errors/mwg-ui.errors.log

                and

                /var/log/mwg-ui/catalina.out

                 

                and check if there is an error that is obvious. In case there is nothing obvious I recommend to file an SR with support, and let them review the logs.

                 

                best,

                  Hi..

                   

                  Troja,

                  i don't know what is the last thing happened because other people work on it. it is a single node.

                   

                  Andre,

                   

                  i couldn't find any errors in the log files but i can put a samples of each command and tell me if you find any strange thing.

                    Hello,

                    java.io.IOException: No space left on device

                     

                    this looks like the reason. Seems the disk is full. Can you check this?

                     

                    Regards,

                      hi..

                       

                      may be it is a point that we must check.. but how can i check the capacity of the hard disk or of that folder which including the java.

                       

                      regards.

                        can you please look at this image of the disk space !!

                          Hello,

                           

                          the /opt partition is out of disk space. This is the partition mainly used by MWG, which is most likely the reason for the probiems you see.

                           

                          Please check the size of the /opt/mwg/log folder, maybe you are storing a lot of log files which fills up the disk. You can run

                           

                          du -s -h

                           

                          to see how big a folder is.

                           

                          Best,

                          Andre
