Centos is killing share server

I have a centos 7 based webserver that must access (and display) pdf files from windows share server. Problem is that its killing webserwer even when webacess is idle (apache stoped). I have figured out (maybe I'm wrong) that this is most likely gnome problem that has a tracker this is what I did: 1) added exclusion in PRUNEPATCHS (this worked for some time) 2) disabled all search in gnome (by clicking) 3) stoped gnome: service gdm stop 4) sudo tracker stautus say all is indexed, or gives D-Bus / X11 / $DISPLAY error (usually it works from gnome terminal, but not putty terminal) Unplugging server network cable stops problem immediately :). Restarting works for some time.
