openlitespeed gets stuck all the time. v1.6.8

I installed cyberpanel + openlitespeed v1.6.8 on my server. But it hangs all the time. I have to restart openlitespeed every time. Problem Resolves When Restarting. but after a while it was the same again.
I have the same problem. Ver. 1.6.21.
should I use the command like this? :
/usr/local/lsws/admin/misc/ -e 1.6.21

thank you
Best Regards
