Atlas update panel

I have atlas update panel which works perfect for couple of hours or even a day or two.

Then it stops render part of page when trigger fires submit.

Just render nothing.

And that happens on all of my pages, where I use atlas.

What that could be?

I tried to create and define triggers in page_init event but still the same.

And I can't even test this behaviour because on the beggining it works.

Otherwise, I have to remove atlas from all pages because my users are complaining.

Any idea?

Got a question, maybe not even related. When you see the problem is the session timeout? Got a problem before with the session.
