PHP Custom Sessions Not Working in Plesk

I went and adjusted the expected time out to 4 hours on every domain and on the default settings through Plesk. But it seems that instead of time outs being handled by php, the server runs a cron job that handles the timeouts and ignore php settings. That breaks our apps. Is it there a way to change his?
