I will try to help you I much as I can. Is not really a problem for me to run trace-cmd on all clients as they are all managed with Puppet. I will try as soon as possible. You confirm to me that I need to run "trace-cmd record -e sunrpc:xprt_reserve" on all my clients ? No more flags ? Did you see that I have added the "-e sunrpc:svc_xprt_detach -p function -l nfsd4_destroy_session" flags in my last recorded trace ? Do I need to add new one for the next crash ? I will also send to you the dump of current kernel task next time. Regards, Baptiste.
