I am on the v24.02 and idk if this was already fixed, but just posting here to keep track of the stacktrace

I am seeing the similar messages followed by lightningd: gossipd failed (exit status 242), exiting. on v24.08. Happy to share more logs if needed.

Deleting the gossip_store and restarting CLN seems to resolve the issue (until/if it occurs again), but it would be preferred if CLN could prevent or at least detect and deal with the issue (corruption?) rather than crashing.
