    01.close() on a socket sometimes returns an error with
       errno=EAGAIN. Rse server code did not check this error and
       that caused the issue.
    

Problem conclusion

  • 01.Rse server has been updated to retry calling close() for
       sockets when the previous call return errno=EAGAIN.
