    Description

      Directory not accessible. When a CD is typed as follows:
      cd /scratch1/portfolios/NCEPDEV/jcsda/noscrub/Yong.Chen/CRTM_ODPStraining/work_ir_v12.1_Zeus/ECMWF83/iasiB3_metop-a

      The following error is generated after a ~6 minute wait:
      cannot access iasiB3_metop-a: Cannot send after transport endpoint shutdown

      ls of this directory hangs for more than 10 minutes. behavior is not see on any of the parent directories.

      It appears that the MDT gets stuck and the client is eventually evicted. I have kernel messages from the the client as well as debug logs for the client and MDT.
