Hi enzo, since this evening (Sept 9, from about 19:40 CEST) every new Synth deployment of mine fails the same way. Build succeeds, runner starts, finds the class, “Setup successfully complete”, then the log stops and 4-5 minutes later the deployment is marked RUN_FAILED. No traceback at all. Deployments 21393, 21395, 21398 (high-sheep, model 17069) and 21394, 21396, 21397 (reliable-monkey, model 17076). To rule out my code I deployed the unmodified GaussianStepTracker example from crunch-synth as 21397, same result. My tracker also runs fine locally through crunch-model-runner 0.4.2 with the full 30-day tick. Now high-sheep submission 2 is IN_QUARANTINE because of those crashes. Could you check the runner side and lift the quarantine? I have uploaded submission 3 (identical code) and will not redeploy until you say it is safe. status.crunchdao.com also returns 502 right now. Thanks.
