Description

Router logs show a lot of messages being dropped because they have exceeded their deadline:

$ grep -c 'exceeded message deadline' dklog.router.*206*.fmt
dklog.router.485.20240206_113601.fmt:1092
dklog.router.486.20240206_113601.fmt:261
dklog.router.93.20240206_113601.fmt:1127
dklog.router.94.20240206_113601.fmt:1107
$

This is new code added by LU-16303. It is possible that this is causing a regression in this case as some traffic that would normally be forwarded successfully by the router is instead being dropped.

This ticket will track removing this behavior for messages being forwarded.
