rpcmod shows svc_cots_kdup no slots free on Sun ZFS Storage System while using direct NFS feature. 

debug.sys: Jun 28 11:47:01 system1 rpcmod: [ID 851375 kern.warning] WARNING: svc_cots_kdup no slots free
debug.sys: Jun 30 20:41:11 system1  rpcmod: [ID 851375 kern.warning] WARNING: svc_cots_kdup no slots free


On Solaris, it is easy to avoid this by modifying parameters via entries in the /etc/system file.


But on the Sun ZFS Storage Appliance, this workaround is not available.
