<div dir="ltr"><div>Hi Eric,<br><br>Setting to delayed start will not help as the issue is related to Fast Startup which means that the Erlang proces is started (or delayed started) only at some rare occasions eg. I noticed that Windows 10 fully restarted all services when system files were updated by Windows Update. In other words Erlang service is usually not stopped when Windows 10 is being shut down, instead it is put into sleep mode. When computer is turned on again then there is no service start routine involved at all, the process is only put into running mode again.<br><br></div><div>Regards<br></div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature">Pozdrowienia,<br> Przemek D.</div></div>

Windows 10 feature is causing unpredictable Erlang behavior, one example
is that it is causing that service processes are put into some kind of
sleep mode instead of stopping them and starting later. <br>From what I
heard Erlang runtime does not work well when going into sleep mode, some
timers work incorrectly then. I was struggling for almost one year with
RabbitMQ being unresponsive for 2-3h every Monday, now I've found that
Fast Startup is causing such mess.<br><br></div>Currently I'm trying to
find any resources related to Erlang and Fast Startup feature, does
anybody know something about it? How to avoid such issue? Is it possible
to provide some kind of fix in order to prevent such cases for Windows
10 users? Or at least letting them know that they should probably turn
this feature off?<br><br><br clear="all"><div><div class="m_6649849169036556995m_-7851892079068253075gmail-m_4482379761962040449gmail_signature">Regards,<br> Przemek D.</div></div></div>
