Is it normal for a clock drift to occur between 3 and 4 seconds long when generating a diagnostic bundle? The bundle is currently not set to generate a heap dump.

How many threads are in the thread dump? Thread dumps aren't a cheap operation.

I didnt use the thread dump button on the threads page. But if they are included in the diagnostic bundle the threads page lists 648 threads. The diagnostic bundle size is 8 megs zipped. The thread-dump.json file contained in the zip is 1/2 meg and has 11,750 lines.

They are included in the diagnostics bundle. Have you looked inside of one?

the zip file contains 12 files, one of them is called thread-dump.json. I did look inside that file containing 11,750 lines.
