      Description

      W20150409-154729
      clusterName="thor400_92"
      internal_5.0.10-1
      ECLAGENT build internal_5.0.10-1

      The hang of the WU run was encountered by Jennifer.Hennigar@lexisnexis.com. She may have worked around it, but it is a periodic run that may hang every time going forward.

      Whether this is in fact a bug or it is some condition the ECL code created erroneously, please identify what condition causes the hang so we can avoid it.

      Sole matching log line is in dali/base/dadfs.cpp
      WARNLOG("CFileAttrLockBase(%s) blocked for %ds", msg, tm.elapsed()/1000);
