sharing process taking loads of cpu on startup
I am using 15 inch MACBook Pro running on MACOS 10.10.5
On booting the MAC, fans start running at max speed. Checking the CPU temperature it shows it at around 100 degree celsius. Checking the activity monitor as to what is executing i find that sharingd process takes a lot of cpu, it goes upwards of 260 odd percentage during this period. I have disabled file sharing(based on the assumption that sharingd deals with sharing). However the problem did not resolve. I also repaired the disk permissions, reset SMC but to no avail.
Can someone tell me what to do for this issue, is the fan issue related to sharingd or something else.
Thanks,
