I am closing this as a stale operational inquiry rather than an actionable bug. This was a 2021 report of elevated "recv headers compression error" rates with a request to compare notes, and no reproduction or root cause was identified. An HTTP/2 COMPRESSION_ERROR is the response defined by RFC 7541 and RFC 9113 when a client sends a malformed or out-of-sync HPACK dynamic table, so elevated counts almost always point to a misbehaving or abusive client rather than a Traffic Server defect. That matches the observation in this thread that the bulk of the errors came from a single source address. The error handling still behaves this way on current master, and there is no server-side change to make here. If anyone can reproduce a case where Traffic Server itself mishandles valid HPACK input, please open a new issue with a reproduction and I will be glad to look into it. -- This is an automated message from the Apache Git Service.
