      Description

      Customer reportsĀ a certain IO pattern from the client hangs for hours in one read call.

      This is 100% reproducable.

      The actual task carried out is linking some application on lustre, which does only finish after hours and should take seconds.

      When tracing the application whith strace found that the hanging IO is a read().
