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.

Geth's 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.

“Deep froze chain segment”message is followed by message loop should I worry about it? – alper Aug 09 '20 at 14:59
Hmm, not sure. Can't immediately see where that is in the code. So the actual message is "message loop"? – Richard Horrocks Aug 09 '20 at 17:20
Yes keep repeating itself on a mesage loop – alper Aug 09 '20 at 18:07
If you look at the hash ID you'll probably see that the message is not so much repeating itself as repeatedly doing a similar thing. – jorfus Nov 01 '22 at 17:19
