After upgrading our servers on Fir (Sherlock's /scratch) to Lustre 2.12.3 RC1, we are noticing a lot of these messages on all Lustre servers:

LNetError: 49537:0:(peer.c:3451:lnet_peer_ni_add_to_recoveryq_locked()) lpni 10.0.10.201@o2ib7 added to recovery queue. Health = 900

The NIDs reported are our Lustre routers, that are still running 2.12.0+patches (they are on the client clusters).

Attaching logs from all servers as lnet_recoveryq.log

This doesn't seem to have an impact on production and so far 2.12.3 RC1 has been just great for us (and we run it without additional patches now!). Thanks!
