Rebooting fixed the issue (for now). I haven=E2=80=99t = seen such issues before. The system was pulled and reconfigured from master in the last = couple days, and recently added docker-related services. I hadn=E2=80=99t = rebooted into updated kernels in the last few weeks. Other services were still running successfully, so it seems unlikely = that there was some out-of-resources thing going on, but hard to say.
