upgrade to raulk/go-watchdog@v1.0.1
This pulls in the improvements introduced in: - https://github.com/raulk/go-watchdog/releases/tag/v1.0.0 - https://github.com/raulk/go-watchdog/releases/tag/v1.0.1 Lotus tries to initialize the watchdog in the following order of precedence: 1. If a max heap limit has been provided, initialize a heap-driven watchdog. 2. Else, try to initialize a cgroup-driven watchdog. 3. Else, try to initialize a system-driven watchdog. 4. Else, log a warning that the system is flying solo, and return. This PR also enabled automatic heap profile capture when memory usage surpasses 90% of the limit. Profiles are written to <LOTUS_HOME>/heapprof. A single heap profile is captured per episode, with a max of 10 episodes captured during the lifetime of the process. Episode = instance of usage climbing above the 90% threshold.
