I recently spent quite a bit of time searching for a tool to analyse the dumps netdump harvests. The biggest hints are 'a suitable tool such as gdb' (or words to that effect). This would have saved *much* time by saying 'a suitable tool such as the Crash Core Analysis Suite, using gdb'. Additionally, the kernel module prints a message stating that it is trying to handshake/negotiate/authenticate against the client - this should be server, and is misleading.
This has been fixed for some time in RHEL, and we're not updating RHL9 anymore, so I'm going to close this as WONTFIX
