rpcsvchost using 99% CPU !!

on mid 2010 mac mini running 10.9.5 noticed every time cold boot process "rpcsvchost" using 99% of cpu in activity monitor.

times rebooting takes care of it, until sits powered off overnight, on first boot eating 99% again.

have reset smc , pram, turned off unnecessary items still continues.

i've searched online , found few others have had same problem, haven't found answers.

advice appreciated, since think next step may re-loading mavericks.

in advance help.

wow, 100 views , nobody else has seen this.
here's little more info :
reinstalled mavericks last night , seemed better after couple of reboots, today rpcsvchost using 99%.
it's running root, don't think it's startup item particular account.

couple of entries in console it, post , spindump log below.

strange after has been sitting off while.
