Requesting access to debian8-x86 for debugging spooky failures

[addaleax]

Hi everyone! If it’s cool with you, I’d like to try and dig into those spooky no-stack-trace, no-error, no-nothing failures we’ve been seeing on Linux CI machines for a long time now.

I think debian8-x86 was particularly susceptible to this… that could totally just be suspicion, but I guess it would be a good starting point? I’m happy to look into this on any machine on which it has been happening.

This is definitely happening on debian8-x86 often. Here is a overview of most reports:

@BridgeAR Alas, those are all now 404s....

(Ooooohhhhhh...the fact that they're 404s is not important. The fact that they are fully 50% debian8-x86 is the important part. Got it. Sorry for the noise.)

@nodejs/build What’s the process for this? It would be ideal if I could have some time to look into this over the weekend, if that’s possible at all

@addaleax root@169.44.16.126, all yours, just ping nodejs/build here when you're done so someone can clean up, or you're welcome to remove your keys from .ssh/authorized_keys when you don't think you need it anymore.

[addaleax]

I think I figured out everything I can in nodejs/node#19903 (comment). I’d like to wait for another opinion or so, but generally I should be done with access here. If somebody else does remove me before that (which is completely fine), please make sure to remove ~iojs/debug-18998/ – it’s 1.6 GB of debugging stuff. :)

[addaleax]

Okay, I’ve removed my own access now. Thanks everyone!
