Hi @leo_woerteler,
We have significant amount of on-prem resources due to past investment decisions. I have been running the free KNIME AP on a Windows Server 2016.
Most of the KNIME processes are scheduled in Microsoft Task Scheduler using the technique described at FAQ | KNIME
I have .bat files containing those suggested command prompt lines set up as Microsoft Task Scheduler Actions. Multiple KNIME tasks in there may run at the same time.
In addition to running background Task Scheduler KNIME tasks simultaneously. I also sometimes open KNIME AP interactively to edit a workflow or to troubleshoot problems with the background tasks. This has been working just fine up to KNIME 5.4.4.
Starting in KNIME 5.5. If there is a KNIME task running in the background, when I open KNIME AP interactively, I will see the splash screen and the workspace selection window, but after selecting a workspace, KNIME would never open. I also saw failed tasks related to those background KNIME tasks that run simultaneously.
After downgrading to KNIME 5.4.4, the tasks have been running just fine.
Please let me know if you need more info from me. Iām sorry for freeloading your software, but Iām trying to make up for it by advocating for KNIME in Reddit.
