Hi,
I'm giving a try to 6.2 and at startup I can see a critical error on TIRPC side:
ganesha.nfsd-35296[main] rpc :TIRPC :CRIT :svc_rqst_hook_events: 0x760215596000 fd 1024
xp_refcnt 1 sr_rec 0x76021519a230 evchan 2 ev_refcnt 3 epoll_fd 40 control fd pair (38:39)
direction in hook failed (9)
This error is not visible when I'm activating FULL_DEBUG on TIRPC so I guess
that's a race.
What I've found is rec->xprt.xp_fd == 1024 and it's the value set in
svc_raw_ncreate (FD_SETSIZE) when srp == NULL
Here is the backtrace when the error occurs:

This doesn't look like having consequences on the next requests but should I worry ?
I'm not familiar enough with ntirpc internals but if you need something to help with
investigation let me know what I can do.
Thanks,
Olivier
