I have an application that is extremely slow to exit at times. On hitting the escape key from the app, it takes 10-15 seconds before the device homescreen shows up. During this time the application is stuck and the device appears to be completely non-responsive. None of the key presses do anything.
This does not happed all the time, only certain times. I hooked up my device to a simulator and saw that the OS prints muiltiple messages stating FS: CLEAN to the console during this time. There are two numbers in brackets after. For Example
FS: CLEAN(37 3)
FS: CLEAN(514 3)
FS: CLEAN(413 3)
FS: CLEAN(175 3)
These messages are not present when the app exits right away.
I have seen the behaviour on a Bold device (v126.96.36.1997) as well as a Curve 8900 (v188.8.131.52).
I was wondering if anyone knows what the FS: CLEAN routine is and how to get around it?
