PT 11.2 hangs (Mac beachball) on audio file import

[TomLewis]

Hello,

We upgraded from 11.1.3 to 11.2 on Tuesday. Since then I have been experiencing a mac hang (Pro Tools - not Responding) when importing sfx files from a Mac share. This is happening intermittently in two audio post rooms. No rhyme to it other than it seems to be happening when PTs is creating the wav form and updating the waveform cash. I say this because when I finally am able to recover the session, I have to wait for the wave forms of the entire session to be redrawn.
Anybody else having this problem?

Both rooms have PT-HDX on Mac Mini 16GB ram with expansion chassis, Mountainlion OS, ISIS shared storage, A mac mini with a raid 5 storage share for sound fx. (Sound fx share set up as transfer only in workspace)
