I troubleshooted some more, and it looks like I may have resolved the issue.
For an unknown reason, suspend/hibernation service was enabled on this server. It looked similar to this issue here https://bbs.archlinux.org/viewtopic.php?id=269203, where a race condition causes CPUs to freeze upon resuming from a suspend state. I disabled suspend services and I have not seen another occurrence of the issue yet.
