NT8 Low CPU usage, too low.

[giogio1]

NT8 latest version, running a chart stuck on "Calculating" while the CPU remains almost idle with NT8 taking less than 1% of the CPU (16 cores).
Anyone has an idea what this could be?

Hello giogio1,
Thank you for your post.

Let's try testing your platform in Safe Mode to verify if this behavior is being caused by a 3rd-party add-on using the steps below.

Safe Mode will prevent NinjaTrader from:

• Loading workspaces and connecting on start-up.
• Loading custom assemblies (i.e. 3rd-party add-ons and NinjaScripts)
• Getting instrument updates from the server

To enable Safe Mode, please use the following steps:

• Shut down NinjaTrader.
• Hold the CTRL key and double-click the NinjaTrader icon.
• Keep holding the CTRL key until you see the Control Center.
• You may then verify you are in Safe Mode by going to Help -> About.

Once you have opened the platform in Safe Mode:

• Reconnect to your Data Provider
• Please open a new chart with no custom bar types/indicators/templates and test for issues.

Does the behavior persist on this blank Workspace in Safe Mode?

• If not, please try opening your previous workspace by going to the Control Center > Workspaces drop-down. It may already show as being open. Hit 'close' and do not save and then re-open it again for your windows to re-appear. You will notice that no 3rd-party add-ons are running in Safe Mode.

Does the behavior return on your regular Workspace in Safe Mode?

• If not, restart NinjaTrader, and test for the behavior on your Workspace normally once more with your 3rd-party add-ons available. If this reintroduces issues, I suggest rebuilding your workspace, adding 1 add-on at a time.
• Please keep track of what add-ons you add back in to identify the cause of the behavior if it returns.

If it does not return, it indicates the error was isolated only to your other Workspace. I also suggest making a backup of your workspace so we can restore a working version of it if the issue returns. You will want to keep this backup file on an external hard drive or uploaded to a cloud drive such as Google Drive, Dropbox, or OneDrive.

To create a backup, go to the Control Center > Tools > Export > Backup File. Additional information about backups may be read in our Help Guide linked below.

Please let me know the results of this test. I look forward to your response.

Thank You for your reply. It turned out that I needed to delete the cache folder of the db directory. I think it got corrupted.
