In our QlikView installation we have two frontend servers running QVS, and a backend server running publisher. (QlikView version 11.2 SR3, all servers: 2008 R).
Since yesterday no task is able to run. No error message is registered in any log file! When starting a reload task, it runs endless! Reload tasks that earlier only ran in 15-20 minutes to complete, are now running for hours!
It does not look like being a CPU or RAM issue while there are a lot of free RAM and memory on the servers.
Do you have any idea or suggestion for how I should find the root cause?
