I didn't find a specific way to reproduce this yet, maybe when my computer goes from sleep to awake but it happened many time.

Once this error happens, then I have it non-stop and the marketplace service becomes useless

even my calls are rejected, this is not only the polling.

The percentage is really close to 100% but without any explanation. The problem is still unclear but we might have some solution to at least improve it if we don't find the source of the problem:

I let the core runs on my macbook since yesterday with multiple change of location (so no more wifi).

I think I was able to reproduce the problem in a shorter time:
