Xibo inactive after a while without logging in

Dear, good afternoon.

I have a xibo Version 2.3.8 installed on a Centos7, it is working fine, but I have a problem, if I stay for example a week without touching the web page, it is extremely slow, many times the page doesn’t even load. I restarted the Apache service and it doesn’t work. Sometimes I have to shut down the server and reconnect to open the browser. I think this is strange, it shouldn’t be shared like that.

To solve the access problem at this point, I had to reinstall Apache, only then did I get web access. What could be happening?

Anyone with this problem?
