Calendar Agent keeps crashing every minute causing hang ups (Beachballs)

Question

Hi All-
Config:
MacBook Pro 8,2 (early 2011)
8Gb RAM/ 1Tb SSD/ 10.10.2/ 1000BaseT ethernet (to cable modem with speeds > 8Mbps to dslreports.com)
This machine was a dog with its OEM 750Gb HD so I replaced it with an 850 EVO 1Tb.  And now despite Yosemite, it screams..well for a week or two it did...
Despite the new install (but I did - probably mistakenly - use my Time Machine back up to reload our user accounts) of Yosemite (yuck).  While the machine is now moving at about 10x faster than its prior incarnation (before SSD upgrade), I noticed that Calendar kept hanging and causing the machine to slow down only days after this new install.
I included the ever repeating console messages below with the crash and its craziness below.
I am going now to rip out all my calendar preferences on this account and caches and see if that helps, but this is kinda nuts.
If anyone has any ideas, let me know please!
Thanks!
Yosemite is killing me:

Answer 1

I solved my problem for now (see bellow).
I think its not some users problem. If its happening to some users (we dont know how many read but dont write in this discussion groups, we are the visible part of the iceberg!). This kind of stuff shouldnt happen. If its happening than its a bug, and is also happening to me.
I have one ipad2 and one iphone4, and having same problems with icloud.
Cant use email and contacts after icloud and cant also turn them off in icloud.
see the emails "loading" forever and the contacts and bookmarks "turning off" all night long and nothing happening.
Found this in another site that helped me, but I think I will keep email and contacts off, out of the icloud, until I understand what is going on.
I just had the same problem . I went onto my iPad and iPhone 4(updated to ios5),
Go to settings
Select iCloud
Delete account
You can choose to save or delete contacts, calendars and reminders
Reboot your device
Then add iCloud account by following steps 1-3 then use your apple ID and password to set up
Turn everything in iCloud back on. In a few moments, you should be up and running
I turned the email and contacts off (this time I was abble to do it) and now my old emails (gmail) and contacts are working.
