This has been observed on Telos, WAX, and EOS. Nodes with enable-account-queries=true went into 100% CPU usage and stopped responding on HTTP requests.

The triggering event is likely related to a high intensity of forks. Nodes in different parts of the world stopped working at the same block number. It also included internal nodes that are not exposed to public, but having the account queries enabled.

at Mar 2 12:41:04 UTC, EOS Mainnet nodes with account queries enabled went in an infinite loop again. It was a short period of empty blocks and heavy forks.

there weren't many forks, but it was a period of blocks that were almost empty
