a4j:poll "stops" after a while

[egesuato]

I have an a4j:poll defined without a timeout but in certain cases it seems that it stops working correctly.

It seems that the polling doesn't work anymore after 25-30 seconds but i don't have a timeout and the "enabled" tag isn't defined to false.

The problem is on Internet Explorer 7 (i have to support only this browser)  and i'm using richfaces 3.1.6. The problem is only in certain cases that i don't know. Have you got a similar experience ? When does the a4j:poll stop working ?

What i know is that after a while, the polling doesn't reach the server ..

Here the code:

<a4j:poll id="poolControlloStampa" interval="1000"

actionListener="#{controlloStampa.controlloDiStampa}"

enabled="#{controlloStampa.controlloStampaEnabled}"

reRender="panelStampa,formsDiStampa,actions" />

Thanks for any help.

could be problems if some concurrent requests sent in the same time.
