Elastic Audio Freezes/Hangs Pro Tools

[critza]

Hello, i have been experiencing this issue with both my computers and now i am working on a song, and in 15 minutes Pro Tools has crashed/hanged twice.
I activate Elastic Audio on a track , set it to ticks and start putting out warp markers after it has analyzed the audio, and suddenly i get the beachball and pro tools stops responding. I have left it on for minutes and then i have to force quit pro tools and restart it.

I am now on a

Mac Pro 2013
12 Core 2.7GHz
16GB Ram

HD Native (in a Sonnet Echo Express SE II Thunderbolt 2) + Omni

Recording drive
OWC Thunderbay 4 with 2 Samsung EVO 256GB in RAID 1

Pro Tools 10.3.9
OSX 10.9.3

I have Pro tools set to Autosave 3 minute intervals. Havent tested if this could be causing the problem, actually i dont really feel like spending time on doing this, id rather make music.

I have another computer at home and i have encountered this error on this machine as well.

Anyone have similar problems?
