[DontPush OzoneLayer] Failed to send heartbeat after browser/web page close

liny lin
9 years ago Apr 20, 2012 2:03am

Hi,

I noticed a "Failed to send heartbeat" exception after I closed main web page of my web application via closing browser or browser tab.
My question is:

  1. Is it related to "connectionGuardTimeout"?
  2. Will it cause any side effect? It's just normal, right?
<init-param>
		<description>Used by Vaadin Addon "DontPush Ozonelayer"
		    This is optional parameter that control the
			timeout before "Connection guard" is for end user. If you
			have lots of synchronous tasks that take long time, you might
			want to increase this value to avoid non-intentional red screens.
			Default value is 5 seconds.
		</description>
		<param-name>connectionGuardTimeout</param-name>
		<param-value>10</param-value>
	</init-param>

Below are the exception logs:

Hi,

To me that looks quite harmless. Have you check Atmosphere projects latest fixes? This might have bee fixed already there. Ozonelayer add-on is bit behind currently.
