[Q] SGS II reboots constantly, Please help [SOLVED] - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
I'm on KE7, rooted and CF-Root 3.6 with CWM .
My phone has tendency to reboot at will after launching two or 3 different applications or at times just as soon as i start an application (any) the screen goes black for 3-4 seconds in frozen state and the phone reboots.
I can reproduce the issue at will, it happens so easily that its becoming very frustrating.
I attached two full logcats and have pasted parts i think are relevant here in the thread . After the startup sequence was fully done, i started the logcat and started Root explorer for the first log cat (which immediately restarted the phone) . And for the second logcat i started aTrackDog with same result.
This happens randomly, sometimes its ok for 6-7 hours but as soon as i start using the phone reboots start happening .
Can some please help me to determine the cause?

Does it do it with a factory reset without root or too many apps?

---

Too many apps? I have around 20, but not all running the same time. I had it rotted since i've got it but rooting or having too many apps can't be the cause otherwise there would be million posts on XDA about it.

---

This started happening to me after installing dropbox. I promptly uninstalled it and the problem went away. It could be an application you have installed.

No this isn't the case, mine happens with any app randomly as it feels like, many popular apps including hence why i included logcats of RootExplorer because for many it runs fine. Issue is somewhere else.
could it be my Lexar 32GB Class 10 SD card causing the issue? IS there a way to test it?

Take the SD-card out and test the phone ??

---

Thats the thing, its not any specific app, but mine reboots when I start installing stuff. When factory-reset it works for at least 3 - 4 days which is why I am not sending it back straight away, samsung wouldnt be able to reproduce it with a factory reset phone. I am still running tests but all these issues seem like race conditions or ram issues (even though I dont see any ram issues in logcat)

---

i'm convinced my issues is the same as here :
Lexar 32GB Card and will follow steps there to see if it'll be fixed.

---

Nope it's not your class 10 lexar. I have the 32gig one as well. No reboots. Unless the card is defective.

I might have phrased it wrong but i didn't really know what was wrong in the beginning. It has more to do with partition of the sdcard rather than sdcard itself. having done what was suggested here my phone feels like a new beast, gone the freezes , reboots...etc
