I've been running 2.4.44 with the test patch since May and haven't seen a crash since, for what that's worth. We upgraded to 2.4.45 last week, without that patch. I'm going to see if the crash shows up again, and if it does, apply the patch to 2.4.45 and see if it goes away again.

Well, since upgrading, I've now seen two crashes; I don't have it compiled with debugging right now so the trace is limited:

but it looks like the same issue to me. I'm going to go ahead and recompile 2.4.45 with the ignore-invalid-accesslog-ops.patch and run that for a while and see what happens.

Thanks...
