We are using Netapp NFS server on server side. No, it is for the client. However, as far as I know, a Netapp Filer never generates a NFSERR_BADSESSION error (except maybe if you were using a post-July 10. 2022 client), so the patch probably doesn't affect you. (Get rid of "soft" and you should be happy.) rick thanks, Ganbold thanks a lot, Ganboldhelp
