  01.missing quotes in sample CGI_ISPPREF definition
  02.RDz client sends a client certificate to the server but the
     server fails to read the certificate due to a timing issue.
  03.The RDz server specify 25 as the number of the buffers for
     CVAFFILT API call. The small number of the buffers increses
     the number of CVAFFILT API calls.
  04.There is not enough trace to show why a new threadpool server
     is started.
  05.Open RSE thread and MVSminer thread are in contention in
     writing traces onto standard.out.
  06.When RDz server executes listds command via TSO ISPF gateway,
     the ISPF gateway creates a temporary dataset and owns it
     during the search process.
  07.The Remote Search on MVS filters had unnecessary steps which
     tended to write many log lines. So the log file was full and
     the server couldn't return the response.
  08.The command for showing data sets couldn't handle multiple
     filter strings in one RSE-filter adequately.
  09.The line information objects of the content search were
     persisted in the server.
  10.enhancement to remove usage of volume RESERVE
  

Problem conclusion

• 01.added quotes in sample CGI_ISPPREF definition
     CGI_ISPPREF="&SYSPREF..ISPF.VCMISPF"
  02.RDz server must wait for the client certificate to reach the
     server.
  03.The use of the maximum buffers (255) would reduce the number
     of CVAFFILT calls by about a factor of 10.
  04.When the heap usage is over the value specified by
     maximum.heap.usage.ratio,the following trace will be logged
     once
    INFO Over MaxHeapUsage: ProcessId=, Memory_Usage=
    When the heap usage become below the threshold after the heap
    usage was over the threshold, the following trace will be
    logged once:
    INFO Below MaxHeapUsage: ProcessId=, Memory_Usage=
  05.Now, MVSminer is changed so that it should not write any data
     onto standard.out.
  06.Now, RDz server skips the allocation error of the reason code
     528: already allocated to the current task .
  07.The server was fixed to remove the unnecessary steps in the
     Remote Search on MVS filters.
  08.The RDz server and client were fixed to support the command
     which handled multiple filter strings in one RSE-filter
     adequately.
  09.The RDz server was fixed to remove content line information
     objects after sending them to the client.
