Eset updated to v13.2.16.0 yesterday and last completed a successful definition update over 4 hours ago. Wondering why my PC has slowed to a crawl I opened Resource Monitor to find that ekrn.exe is using over 12GB of physical memory, currently 93% memory usage and still increasing. The Eset tray icon is continuously spinning and the program has been reporting "Module update in progress" for at least the last hour that I am aware of, possibly since the last update check over 4 hours ago for all I know.

I have tried clicking "Cancel Update" but it is not responding.

Current stats for ekrn.exe are

132,933 threads 18.4% CPU

Memory 12,419,948 KB

Going to try restarting my PC now...

Rebooted. Eset has just successfully checked for and completed an update . ekrn.exe  now 125,000 KB memory in use, 0% CPU.

Will see how it goes.

Try collecting logs and share here. It may help ESET troubleshoot the issue even though it may have been fixed on your PC.

This is all I can find. It's from 24 hours ago and I don't know if it's relevant as according to the Eset log EIS successfully updated at 09:48 hrs today.

The application update to was completed at 08:01 yesterday, around 7 hours before this log was created.

I have collected the files from C:\ProgramData\Microsoft\Windows\WER\ referred to below and can send them to Eset if required.

Hello @Phil_S,

we would need a dump of the process memory to check what is going on there.

If you see again such high resource consumption , please navigate to Advances settings -> Tools -> Diagnostics and set the dump type to Full. Hit the Create button next to Create diagnostic dump option.

Once complete, create a log with ESET Log Collector, upload the generated archive to a safe location and send me a private message with the download details to check.

Thanks @Peter Randziak,

So far, everything is normal since the reboot. If it happens again I'll do as you suggest, but I thought I ought to mention it in case there was an unknown issue with the new release, having found a similar post in the NOD32 AV forum.

@Marcos, files attached. Thank you.

Hello @Phil_S,

thank you for the log file, but sadly the dump file is empty 😞 so we cannot analyze it...

Please monitor the situation and in case you encounter the issue again, provide us with logs as described above so we can check what is going on there...
