[NFS-Ganesha-Devel] Re: Issues seen with krb5i and krb5p mounts

We are also seeing the same issue. Thought that after this client patch (it went into 4.20) https://www.spinics.net/lists/linux-nfs/msg69633.html Client would have started to honor the RPCSEC_GSS window but we are hitting this issue even on kernel versions 5.xx The only solution which mitigates it somewhat is to limit the in-flight RPCs that the client can have by tweaking tcp_max_slot_table_entries (for example to 16 or 32) and along with that change the GSS window size in Ganesha to 256. Max_slot_table_entries guarantees the in-flight rpcs, but it doesn't guarantee the sequence limits. For example, if some of the requests take unusually long time than the16 in-flight RPCs can have the sequence numbers which might not fit into 256.
