I have question My geth show me like that "Deep froze chain segment" repeatedly
This is related to Geth's Freezer functionality, which "moves ancient chain segments out of the active database into immutable append-only flat files."
The message you're seeing is informational, so it's nothing to worry about.
freeze() function (in
freezer.go), where that message is output, does the following:
"freeze is a background thread that periodically checks the blockchain for any import progress and moves ancient data from the fast database into the freezer."
Freezer was implemented in PR #17814, and is described in detail in the PR.
