Problem with downloading files from play market and websites

I have nexus 5 (android 4.4.2, TeamWin Recovery Project, root). Recently, problem with downloading files from play market and websites appeared. I see infinite downloading in the play market. I see infinite work of the donwload manager process in the action bar, when I download some stuff from website (for example, when I try to download something from my HTTP local file server). Sometimes I can solve my problem to restart smartphone, to clear data/cache play market app and download manager procces. But the problem occurs again. Also I tried to boot into recovery, clear cache, fix permissions, and reboot. These actions have fixed my problem, but the problem appeared again. (Click on image to show larger preview)
