I am facing this issue after 3 month when i ran the node,

3060102 reversible_guard_exception: Reversible block log usage is at unsafe levels reversible free: 2096992, guard size: 2097152 {"f":2096992,"g":2097152}

1 Answer 1


This is caused by too small of a setting for reversible-blocks-db-size-mb. Increase this value. You likely will also want to increase chain-state-db-size-mb as well.
