Following several days of frequent freezes, I tried changing the following settings
updated in [Logged In Users Only]:
[opcache] original settings

-
added var_dump(opcache_get_status()) to php status page to be able to monitor opcache usage
-
changed warning logs from E_ALL & ~E_DEPRECATED & ~E_STRICT to [Logged In Users Only]
----
noticed [Logged In Users Only] contained a LOT of processes being stopped for tracing
turned off request_slowlog_timeout by setting to 0s in [Logged In Users Only]
had been 4s

I had turned on lightspeed at 1:45 am est , aug 26. Seems like more problems since then.
None of the above seem to help, still getting freezes maybe every 30 minutes. Next will try turning lightspeed off.
Also let on set session.gc_probability = 1 and session.gc_divisor = 1000 in php.ini because discovered ~/tmp is full of thousands of session files, and gc_probability was set to 0.
