No slave scheduler found

[qwebnm]

On November 3rd, QMC Task Error occurred.

When I checked the log of the server manager, I found an engine error, and there are various logs.

1. Restart: Server aborted trying to recover by restart. Reason for restart: No document purge activity for 120 seconds.
2. Core dump: Writing core dump file to C:\ProgramData\Qlik\Sense\Engine\CrashDumps\Coredump_12.811.6_1981428_4294967295.dmp
3. Core dump: Core dump result = 1

Why are you doing this all of a sudden?
I think it was because the memory was high at the time, is that correct?
I'd like to know the cause in more detail.
There are two core dump files, but they come out as a set value and an unrecognized character value.
Should I further analyze the dump file?
I have attached the dump file, so please check it.

Let me know if you know anything.
Thanks & Regards.

Hi Seheon, in the C:\ProgramData\Qlik\Sense\Engine\CrashDumps there should be a .ctx file. This file is readable and could lead you to an app id that is giving you this issue. You can also use the app analyzer to help with analyzing the app.
