I have question My geth show me like that "Deep froze chain segment" repeatedly

What mean??


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?

  • Hmm, not sure. Can't immediately see where that is in the code. So the actual message is "message loop"? Aug 9 '20 at 17:20
  • Yes keep repeating itself on a mesage loop
