Description

I use nfs4 shared with kerberos authentication.
Sometimes the following message appears in the server's logfile:

nfssrv: [ID 474727 kern.notice] NOTICE: Failed to decode arguments for NFS version 4 procedure RFS4_COMPOUND client 192.168.100.10

In addition I get RPC decoding errors ("xdrcall") if I run the nfsstat command.

On the client side I oberserve at the same time that the nfs server is not responding for a while (The clients waits for an answer of a request).
The client is a linux machine which mounts the nfs shares with version 4.0.
If that happens some shares become unaccessible on the client for some users.

Any chance you can get a snoop trace and attach it?
(binary form, i.e. snoop -o nfsbug.snoop ...)

Unfortunately, the message appears only once a day therefore it's hard to capture the right packets.

However, the bug is related to this report maybe:
