Bug Fixes

  • Fixed a critical issue on Mac OS X where Sauce Connect throws a fatal error and terminates. This issue happens when WiFi is temporarily turned off or when the system wakes up from sleep or when internet connectivity is temporarily lost. The fatal error looks like below
    "fatal: morestack on g0"
  • Fixed an issue so that Sauce Connect terminates on startup if pid file location (--pidfile) is inaccessible.
  • Fixed file descriptor leak.
