<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have two rabbitmq servers to form a cluster. It mostly runs great. But sometimes after redeploy, we saw some boot failure error in rabbitmq server log.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The relevant part of the log is shown below. But the problem is that we saw these log messages repeated every 7-8 seconds and can last as long as 80 minutes before rabbit finally start up correctly. During this time any connection to the
rabbitmq cluster will get a disconnected exception.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any idea on what might have caused this problem?<o:p></o:p></p>
