I patched the current Debian stable kernels :

Debian Linux 6.1.0-29-amd64 (= 6.1.123-1) Based on Linux 6.1.120
Debian Linux 6.1.0-30-amd64 (= 6.1.124-1) Based on Linux 6.1.124

with there two commits :

8626664c87ee NFSD: Replace dprintks in nfsd4_cb_sequence_done()
961b4b5e86bf NFSD: Reset cb_seq_status after NFS4ERR_DELAY

Now my two NFS servers are running these patched kernel. I need to wait one week to see If the crash still occur.

Chuck, does this patch may remove the "unrecognized reply" messages from my syslog ?

I see you have improved the backchannel session logging. Did I need to change my trace-record command ?
