PhantomJS + Cron - how to prevent memory overflow?

Question

Task Schedulers

On the server, it is loaded via phantomjs every 10 minutes of the page.
At the same time, after loading the page, they should be unloaded from memory, and not accumulated.
In fact, PhantomJS processes multiply and the server crashes after a while (500).
Are there canonical ways to kill these processes, for example, through the same cron every hour, so that they do not accumulate?

Answer 1

As it turns out, PhantomJS has a memory leak - a classic problem.
I solved it by creating a cron task to kill all PhantomJS processes every hour.
A crutch, but everything works without failures.

Answer 2

It is necessary that there would be page.close(); and exit(); in PhantomJS code
