RhoMobile 4.0 stops working after being not used

We are using RhoElements as a web browser in MC45. We have faced a problem with RE that causes the web application to hang when RE has been running on a device for a while (maybe for hours, over night) but it has not been used. As soon as the RE has started, users are promted to log in using their username and password. Everything works fine if user logs in right after RE has started. But if the login screen has been on the device (for example over night), login seems to be succesfull but user ends up with empty screen instead of the normal menu. This means that RE is causing this for some reason.

I am not a software developer so I don't know how the web application is designed. I have gone through the logs that I can find from the device and I have found something strange that I don't understand.

During this the web application has hanged and user is forced to reboot the deivece. Rest of the log is attached and this part can be found from page line 6041.

What does 'MainWindow| ACTIVATE: 0', 'APP-DEACTIVATED' and 'AppCallbacks| ThreadQueue blocked for 4294967295 seconds...' mean?

Looking at the log, it looks to me like the lines you are looking at were the app exiting (maybe because it detects that the device is about to boot).  You can see it start back up again at 10:27.  I don't see it trying to navigate anywhere before 10:27

Can you try a controlled test, like keep track of when the app first starts up and shows the login page, and when the user tried to login and get the logs from that period so we can see what happened at those times?

One thought comes to mind for me, I'm wondering if the webserver is timing out the request and maybe trying to show a popup on the  device (we do not support popups).  Can you leave a PC on that same login page overnight and see what happens when you try to login in the morning?

This issue needs assistance from Motorola folks.
Lets wait to hear from them.

Thank you.
