KNIME Closing Frequently Even in mid of WF Running.

[Prashant278]

I am facing issue with KNIME that it is getting close disorderly. Sometimes in mid of workflow. Tried with admin login but still same problem. Please find attached log file for the same. Below is the system configuration:

Processor: Intel(R) Core™ i5-10500T CPU @ 2.30GHz 2.30 GHz
Installed RAM: 16.0 GB (15.7 GB usable)
SystemType: 64-bit operating system, x64-based processor

Please help me as its bottleneck for me to proceed with work.

Thanks in Advance.

Hi @Prashant278 -

It’s hard to say based on just the log, without any indication of what you’re trying to do with the workflow. That said, the log has several mentions of Windows Defender. If you are able to temporarily disable that program, does the problem still persist?

Hello,

As @ScottF pointed out, we can see a couple of ERRORs in the logs:

2022-09-29 18:31:49,973 : ERROR : KNIME-Worker-4-Joiner 3:24 : : BufferFromFileIteratorVersion20 : Joiner : 3:24 : Errors while reading row 124841 from file “knime_container_20220929_9235116976056987792.tmp”: null; Suppressing further warnings.

35 java.io.IOException: Unknown shortcut byte ‘-125’

So you might want to look at your input to clear those errors.
However, the real issue you see multiple iterations of is:

58 2022-09-29 20:59:19,350 : ERROR : main : : WindowsDefenderExceptionHandler : : : PowerShell command powershell -inputformat none -outputformat text -NonInteractive -Command Get-Item -Path ‘Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows D efender\Exclusions\Processes’ -ErrorAction Stop | Select-Object -ExpandProperty Property did not terminate successfully.

I recommend looking into whether Adding an exception to Defender for knime.exe as per [1] may help you overcome this issue. It sounds like Defender is stopping something from happening, or some other exception/exclusion is not set up properly.
