ssl.SSLError: [Errno 8] _ssl.c EOF occurred in violation of protocol

[Peter Petrakis]

I get this randomly when I deploy bundles, it's not frequent, but when it comes up it's fatal.

[Kapil Thangavelu (hazmat)]

this is an issue with the state server juju-core ssl impl

[Kapil Thangavelu (hazmat)]

afaik, this is when the state server is shutting down or flapping.

[Aaron Bentley (abentley)]

I think this error should be handled gracefully, e.g. by retrying the connection. Unexpected EOFs are a fact of life when you're working in the cloud.

[Anastasia (anastasia-macmood)]

Considering that there has been complete re-design of state server (controller) behavior for multi-model view of the wold in Juju 2, we believe that this bug is no longer valid.

If you encounter controller failures on shut down, please file a bug against "juju" with relevant logs.
