Black screen while opening sheet (after June 2018 update)

Hi everyone, I am using Qlik Sense Server Enterprise June 2018. After the update, we start to facing this issue.

When trying to open a sheet, screen is freezing. If I refresh the page, screen is opening without freezing. If I not , I must to wait like 5 minutes.

It's not just a page-specific issue. This problem exists in most applications or sheets.

P.S: The server does not meet the recommended system requirements, but in the previous version we did not encounter this problem.

I managed to solve the problem. Just delete the unused connections under Custom Data folders. I deleted all connections expect QvRestConnector. It's working fine for now.
