Qlik suggests - 

"Upgrade to November 2018
The issue is resolved in this version"

Our Qlik Sense server (QAP 6 core license) is at November2018 SR1 level

Despite of that we receive hundreads of errors a day.

Same issue with our QS server as well.

So, they have suggested to increase the RAM.

I think it's not the solution that will fix the issue.

Here a server with 224GB of RAM, only 2 apps 900MB and 80MB, max 100 concurrent users.
