Hi @vrutkovs

Thank you so much for reporting! :) I think it is related to the recent changes in Hypothesis, originally I was assuming it was a thread-safety issue, but as far as I see, you don't use the "-w" CLI option, right?

[vrutkovs]

I have -w 10 set, all params are:

  --show-trace \
  --request-cert /kube_configs/clientCert.pem \
  --request-cert-key /kube_configs/clientKey.pem \
  --request-tls-verify false \
  --junit-xml /results/junit.xml \
  --workers 10 \
  --checks not_a_server_error \
  --report \
  --request-timeout 500 \

Testing if --worker 1 makes a difference.

UPD: Right, its parallelism. Can't make it crash with -w 1

[Stranger6667]

I'll submit a fix upstream - a shared cache causes it, but usually such caches are thread-local in Hypothesis.
