Hello, happened to me too, now a third time. The first two times on 6.1.85 and now on 6.1.90 on the server. Clients are primarily Proxmox hosts running Linux 6.5.13. NFS Version is 4.2.
This didn't happen with a very old kernel 6.1.0-9 from May 2023 which we were running previously. ================================================================================ [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000000b90a020 xid 7aa02cc0 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 0000000012521bac xid db1882c6 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000001983dd82 xid c8e8428b [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000001ed9ceeb xid 9e09a079 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000b65a955d xid 8eee3a15 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000005706134e xid 1de36c93 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000f9d48ca3 xid 366cd575 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000a25621a3 xid 04908592 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000b27bf2f5 xid 2bf8d75e [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000002041e651 xid 331c9f24 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000bb856d0c xid 35c41e07 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000cf8f7523 xid e7ebe821 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 0000000061496440 xid d1e84119 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000bd100f39 xid c2770460 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000001639729a xid 2eb64435 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 0000000031316e4d xid 63f934ac [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000002f831e3b xid e1e5bdff [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000002d3c5c60 xid 89e3910b [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 0000000021afae1a xid e45a86a1 [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000003e5a70d5 xid 933234ed [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 00000000d0dffd1d xid 602eb73f [Wed Jun 26 10:59:34 2024] receive_cb_reply: Got unrecognized reply: calldir 0x1 xpt_bc_xprt 000000006496e8c0 xid 7d3a4d97 [Wed Jun 26 11:03:56 2024] INFO: task nfsd:2007 blocked for more than 120 seconds.
