This bug has been created based on an anonymous crash report requested by the package maintainer. Report URL: https://faf.lab.eng.brq.redhat.com/faf/reports/bthash/1d4275e363d403170b9b63f16bac42c714908444/ we have quite some occurences from 7.5 and 7.6 too. So probably a good candidate to check for 7.7.
Judging by syslog, that system is totally overloaded. Each of the watchdog-caused kills happened after a soft lockup in kernel => not a bug.
