Dear ALL:
I'm porting Froyo now but I met a strange issue. When I pressed
the power button for a while, the device should have show a dialog to
let me choose power off or other options. However, the dialog didn't
show up. Instead of the dialog, I got some error msgs liking
W/WindowManager( 1628): OutOfResourcesException creating surface
I/WindowManager( 1628): Out of memory for surface! Looking for
leaks...
W/WindowManager( 1628): No leaked surfaces; killing applicatons!

W/ActivityManager( 1628): Killing ProcessRecord{43ef8988

W/WindowManager( 1628): Looks like we have reclaimed some memory,
clearing surface for retry.
W/WindowManager( 1628): Due to memory failure, waiting a bit for next

After checking the log , I suspected that it was caused by
surfaceflinger. Then I put some log into some codes that were relative
to Surfaceflinger. I disvoered some clues as below.

As u can see, Android_view_Surface received the correct paramemters
but when it used ibinder to pass the parameters to surfacflinger,
sufaceflinger got the wrong parameters. Since the name field, every
parameters was shifted by 1 size. Therefore, flags became -2 and while
surfaceflinger was parsing the flags, it couldn't find any condition
mathing -2. Thus, OutOfResourcesException happened. I have compared
the source codes about Surfaceflinger, Parcel, ibinder, kernel biner.
They were all the same as common code. I have no idea what happened.
And this only occured when the name field was empty from
Android_view_Surface. The other cases name field would have something
liking app name. Does anybody have any idea of that ?? thanks~~
