OLS keeps reloading every few minutes

OLS status shows:

And sometimes, the process is not really killed, it's stuck there and dead. Then the status showed

Restarting OLS from DirectAdmin didn't help. When it happened, I had to login ssh and killed these processes manually, then started OLS again.

Any idea?
Thank you.

Please check the error and stderr logs and see what happens before the reload.

Nothing appears in error_log and stderr.log. In the syslog, comparing the date time, there are something like this only
