    <p>Hi Strahil</p>
    <p>I have tried a couple of tests of trying to gunzip the file with
      top running on the client (mseas) and on the brick server
      (mseas-data3) and with iotop running on the client (mseas).  I was
      not able to install iotop on the brick server yet (the external
      line is down).  I'll repeat when I fix that problem</p>
    <p>I now can get one of two error messages when gunzip fails:</p>
    <ul><li>gzip:
        /projects/dri_calypso/PE/2019/Apr09/Ens3R200deg001/pe_out.nc.gz:
        File descriptor in bad state</li><ul><li>a new error message<br clear="none">
        </li></ul><li>gzip:
        /projects/dri_calypso/PE/2019/Apr09/Ens3R200deg001/pe_out.nc.gz:
        Transport endpoint is not connected</li><ul><li>the original error message<br clear="none">
        </li></ul></ul>
    <p>What I observed while waiting for gunzip to fail</p>
    <ul><li>top</li><ul><li>no significant load (usually less than 0.1) on both
          machines.</li><li>zero IO-wait on both machines</li></ul><li>iotop (only running on the client)</li><ul><li>nothing related to gluster showing up in the display at all</li></ul></ul>
    <p>I include below what I found in the log files again corresponding
      to these tests (and what I see in dmesg on the brick-server
      related to gluster, nothing showed up on the client)</p>
    <p>Please let me know what I should try next.</p>
