Bootstrapping azure causes memory to fill

[Dan Chapman ]

When running 'juju bootstrap -e azure' my memory is completely filling up (16GB +8GB swap) within about 1-2 minutes, leaving me with an unusable system. I have also tried using the package in the ppa which I experienced the same issue.

Is there any specific logs you need with this bug report?? If so i will get those to you asap.

FIX:
The problem is caused by using the *.cer. Azure wants the *.pem file. The azure documentation from MS is vague. Users of the SDKs also make this mistake.

The juju azure-provider could check if the file is a pem and raise an error early.

We have never seen this in automated or manual testing, both of which use machines with 2-4Gs of memory. Does this happen with 1.16.5?

[Dave Cheney (dave-cheney)]

I'm very certain this will be a bug in printing an error message who's
string (Error()) routine calls itself, recursively.

So it only happens during an error, and make things infinitely worse

@jamespage, if you can reproduce the issue, can you hit the process with a
SIGQUIT and post whatever output you can, the stack trace will point to the
offending code.

Had the same issue and a debugging session demonstrated that the problem occurs while marshalling the environInfo management-certificate setting. It ended up I was using the wrong path to the certificate (management-certificate-path pointed to the cer file rather than the pem file).
I'd suggest to clarify that in the documentation, which seems at least ambiguous: https://juju.ubuntu.com/docs/config-azure.html
IMHO we should also improve unexpected values serialization in juju.

Status changed to 'Confirmed' because the bug affects multiple users.
