One of our application server had BSOD for the past 2 weeks with a similar error. There were a lot of event id complaining “The server was unable to allocate from the system nonpaged pool because the pool was empty” before the server crashed.
The BSOD error was 0×0000001e (0xc0000006, 0xa0001d52, 0×00000000, 0×00370cb4).
The application team was quie insistent that their application couldn’t be the cause of the error and so I raised an issue with Microsoft to help me have a look and here was the result:
> BSOD code was as follows
