Hello,

Thank you for posting in Microsoft Community forum.

Based on the description, I understand your question is related to a database connection error and a faulting module named ntdll.dll. This could be caused by a variety of factors, such as outdated drivers, corrupt system files, or hardware issues.

1. Check for any available updates for your Windows Server 2019 and install them.

2. Update your drivers, especially the ones related to your hardware components.
3. Run a system file checker (SFC) scan to check for any corrupt system files and repair them if necessary.

open the Command Prompt as an administrator, type "sfc /scannow" and press Enter.

4. Check your hardware components, such as your RAM and hard drive, for any issues.

Have a nice day. 

Best Regards,

Hi Molly,

We have already updated all the patches and run sfc/scannow in the server, but still, the problem has not been resolved, at the time of the issue when we tried to kill the process who are consuming the CPU even if it didn't work.. it is showing the process/services killed but it is kept on showing in task manager.

We have tried below steps to resolve the issue:-

1. Increase the size of virtual memory.
2. Certain optimization In the ISS setting
