Default [Q] Sprint Marquee reset during call, errlog attached

My sprint Marquee started to develop an annoying problem: reset during call. I cannot post link yet, but there are several other Marquee users reported same problem in androidcentral forum.

It's not a complete reset, but the screen will turn blank and not responsive, only the four button will flash the led. After 1 minute it will come back.

I knew I can try to restore to factory default, but after a little search, I saw many android phone user met this problem, and many of them were using factory default settings. So I decided to uninstall apps and install an error log app for next reset.

Yesterday there was another reset, and I saved the error log immediately after the reset. But I'm not sure if the error caused the reset can be recorded.

Hear are the error log, anybody can have a look at it and get some ideas about the problem?

For the apps I installed in my Sprint marquee:
It was rooted. No task killer. Used to freeze sprint bloatware with Ti backup but I uninstalled Ti backup earlier.
Was using Go launcher, then zeam launcher.
Was using dialer one, then back to stock dialer. the call log was limited to 7 days. -- I was guessing it could be the call log too long.

For the error log files:
alogcat.2012-01-26-18-06-31-error.txt
this one was generated right after the reset, but I didn't know how to turn on time display at that time.

The reset occurred on about 18:06.

alogcat.2012-01-27-00-00-52-warning.txt
this one was generated later at night with time displayed. It's a log on warning level.
