Sunil,<br><br> Can I configure this heartbeat to use a high priority (realtime) schedulling?<br><br> If I simply increase the timeout it still could timeout on heavy I/O situations, like several different threads queuing large amounts of writes. The kernel should know this is a high priority write so that it is put ahead of the queue.<br><br>Regards,<br>Luis<br><br><b><i>Sunil Mushran <Sunil.Mushran@oracle.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> The older 12 sec default timeout was too low.
