      These occurrences share similar characteristics on the same patch build:

      • debug-compile-sspi-openssl-patch failed after replying to an isMaster command due to the mock server still running after shutdown.
      • release-compile failed to receive a request to the mock server after receiving an isMaster on the mock server.
