                      <div dir="ltr">Hi,
                        <div><br>
                        </div>
                        <div>I appear to have a memory leak with a
                          replica 3 arbiter 1 configuration of gluster.
                          I have a data brick and an arbiter brick on
                          one server, and another server with the last
                          data brick. The more I write files to gluster
                          in this configuration, the more memory the
                          arbiter brick process takes up.</div>
                        <div><br>
                        </div>
                        <div>I am able to reproduce this issue by first
                          setting up a replica 3 arbiter 1 configuration
                          and then using the following bash script to
                          create 10,000 200kB files, delete those files,
                          and run forever:</div>
                        <div><br>
                        </div>
                        <div>
                          <div>while true ; do</div>
                          <div>  for i in {1..10000} ; do</div>
                          <div>    dd if=/dev/urandom bs=200K count=1
                            of=$TEST_FILES_DIR/file$i</div>
                          <div>  done</div>
                          <div>  rm -rf $TEST_FILES_DIR/*<br>

                        <div>After about 3 days of this script running

                        </div>
                        <div><br>
                        </div>
                        <div>As you can see one of the brick processes
                          is using over 2 gigabytes of memory.</div>
                        <div><br>
                        </div>
                        <div>One work-around for this is to kill the
                          arbiter brick process and restart the gluster
                          daemon. This restarts arbiter brick process
                          and its memory usage goes back down to a
                          reasonable level. However I would rather not
                          kill the arbiter brick every week for
                          production environments.</div>
                        <div><br>
                        </div>
                        <div>Has anyone seen this issue before and is
                          there a known work-around/fix?</div>
