@CyrusNajmabadi can you take a peek at this, since @heejaechang is OOF right now.

@Pilchie Pilchie added Bug Tenet-Reliability Customer telemetry indicates that the product is failing in a crash/hang/dataloss manner. labels Apr 11, 2017

Is there a dump for this?

Nope :(

However, @Pilchie taught me how to fish, and in the future I'll get dumps automatically when we crash.

I have a dump, but it will take me an entire day to upload, so please tell if if you need it and I'll upload it.

I added explicit FailFast rather than Contract.False to get better dump. try use latest drop and let me know if it happens again. for now. not enough info to know why that situation has happened.

@davkean nice, can you give me the dump?

@heejaechang Before I do that (it takes me an entire day to upload to internet speed) - will a dump with the existing code (without a FailFast) be good enough?

no. that already lost context. I need a dump at the location where it is happening.

Then my dump won't help.

oh. this is different issue then Dispose issue.

this should be fixed either by what @sharwell did, or #19466 or #19311

can't remember which bug specifically addressed this cause. but one of them fixed it.
