Comment 103 for bug 1124250

Sorry, I missed an 's' (not an 'e') in the command (cut/paste problem), so the
command is actually:

# echo "10000" > /proc/sys/kernel/keys/root_maxkeys

perhaps after the command it is better if you clean the keys with

# nfsidmap -c

This does the trick for us, it is strange that it does not change anything
to you! If the change works, then you can make this happen at boot by creating
a file in /etc/sysctl.d/ with a name like "99-local.conf" containing

# Keys for nfs
kernel.keys.root_maxkeys = 10000
