    Description

      Scenario: 2 UMs and 3 PMs
      Mode 1: UM gets the file to CPIMPORT to all nodes.

      The table lock is not cleared because, the process triggered from UM is not cleared. When UM creates a CPIMPORT to all its PM nodes, it creates a PID attached to the CPIMPORT which locks the table. It keeps it even if the cpimport is successful. May be, the acknowledgement from PMs is not reaching UM at sometimes, resulting in locked table.

      Attached is the complete details.
