Sean,
I'm pretty sure this is not the case for my environment, as we have
less then 100 groups in total.
Regards,
Vladimir.

Michael,
I've posted an email with the same question here a few weeks ago, but I
haven't been able to investigate what the problem is. The only
difference in my setup, that servers have kernel 2.6.36 the rest is
exactly the same and exactly the same error. See thread with the subject
"rpc.svcgssd problem after updating client 1.2.2->1.2.3".
I think the problem here is the same one we were experiencing, with
large group memberships causing invalid writes to the procfs rpc channel
files. If you strace rpc.svcgssd (or rpc.mountd, you should see it
there too I think), you should see the write() calls being split into
multiple 1024-byte sized writes, each of which get EINVAL (or -EINVAL, I
forget) returned.
I've submitted a patch for that last week, which is waiting on
inclusion. If you want to verify, please look back in the archive and
try the patch submitted in the mail with subject:
[PATCH v2] nfs-utils: Increase the stdio file buffer size for procfs
files
It seems to work here, I'd appreciate if you could try it out and let me
know if it works for you too :)
BR
Sean
