Tvheadend

Hi, need some help with my tvheadend setup.
Tvheadend stop working few time a day, and the log doesn't say much. the only "error" that i can see in the log is a lot of PID 1B60 CC error 8 != 9:
Aug 31 16:54:14 ubuntu tvheadend[14626]: tbl-csa: ecm: 10778H in Tv: PID 1BE6 CC error 10 != 11
Aug 31 16:54:14 ubuntu tvheadend[14626]: tbl-csa: emm: 10778H in Tv: PID 1BE6 CC error 10 != 11

Aug 31 16:54:14 ubuntu tvheadend[14626]: tbl-csa: emm: 12015H in Tv: PID 1C0A CC error 9 != 10

im a ubuntu 14.04.5 LTS with HTS Tvheadend 4.3-949~gebd3391 and using tbs 6909 as tv tuners..
i have look at the syslog and tvheadend debug file, but it doesnt give any error or cuase/reason for why tvheadend stops..

is there any way to make a cron job that monitors tvheadend service and restarts it?
