    Check your UPDATE process is up and running or not?

    Go to SM13 and check under Administration area, if it is showing stopped just restart the process.

    If you are in non peak hours, just restart the application.....that can help you to get fresh processes without any error and inturruptioon

      Hi ,

      As you said that the Server becomes slow for a short time period and after some times it becomes normal ,

      So there could be possibilty of network issues at ur end , some packets might gets lost

    I would suggest to check the following notes for the known problems on ENQ:

    1131092 Enqueue work processes hang in status "Running"

    1304197 Hanging enqueue processes; duplicate releases of WPCA blocks

    Hope it helps.
