Android Question [SOLVED] Strange problem : app freeze

I have a problem with my app

I have more than one page, using TabStrip lib to change page.

I wait message from TCIP and RS-232 and have same services witch have timers inside.

The app work well, but i have a freeze of system, tablet is locked for some minutes, then go slow and finally return to normal speed.

I have tryed to connect via USB to debug and removing filter flag i have this message from Tablet :
