ProTools HD 10 Crashing, Hanging, Random Loops, Errors

Hi



Pro Tools system has started to act up over the last few months. . . not sure what to attribute it to. Close to unusable right now, with multiple problems per hour.



Symptoms are:

1. Randomly goes into a loop for about 5 second, while recording or playing back, and then display an error - 9128 (running out of CPU power), but CPU is basically at 5% or less.


2. Random error - 9162


3. ProTools Crash with Dump/Log. . . sometimes in the middle of using ProTools, or when exiting ProTools. Restart always required because a restart of ProTools will result in a total freeze up.


4. Beachball forever, often when editing with Elastic time.


5. Playback just stops working. . . press Play and light goes green, but will not roll.


6. Just had some very loud noise show up on a bunch of tracks that previously played fine. Did a recalc of waveforms and it showed that the waveform was totally spiked across about 6 different tracks. . . .audio was fine minutes earlier, as it was days ago.

System Info:

• ProTools HD 10.3.8


• HD 3 PCI-e with 2 x 192i/o + ADAT bridge (to 02R for cue mixes)


• OS X 10.7.5


• Mac Pro 2.66 (Quad Core Original) with SSD system disk (OWC), 8GB RAM, sessions on separate drive on internal sled.http://ift.tt/1hz8DXu

Done all the usual, trash prefs, volumes, digi database files, did a clean OSX and ProTools install awhile ago, etc. . .

Repair permissions finds a bunch of trouble, says it Repairs, but every time you run repair perms, it is the same long list of files. . . not sure what to make of this.

Drive Genius seems to think a bunch of preference files are corrupted. . . not sure what to make of this either and I don't want to blow things up. . . it feels like a false positive.

Ran Cocktail on System

Used System for a few hours and experienced multiple loop freezes and app crashes with dumps.

Rember Memory test done - showed no problems, but it only checks unused RAM so not a great test. . .

Digitest - no problems.



Is my next move to uninstall ProTools. . . reinstall OS X 10.7.x (I had OS X 10.7.5 installed, but I just noticed compatibility is only up to 10.7.4), and reinstall ProTools 10.3.x? and if so are all my plugins and Virtual Instruments still going to work? or are there still a few more steps before that? (I am rusty at this, and I have not seen a comprehensive document with the step-by-steps).



I need to get stable, hopefully without a fresh install of everything. . . which, with all plugins, virtual instrument, and libraries, takes about 30 hours + of my time. . . really hoping to avoid that colossal waste of time.



Any suggestions on best next steps, or pointer to comprehensive info, would be appreciated. . .
