-6101 Error...driving me batty.

[Scott Stillwell]

Sawtooth G4, 1 processor @ 1.3GHz, 2MB L3 cache
1.5GB RAM
2 x 120GB internal drives with 8MB cache (1 for OS/programs, 1 for Audio data/projects)
1 x 200GB Firewire drive (LaCie) for project archival
1 x DVD+/-RW,CD-RW (TDK 440N)
1 x SuperDrive

M-Audio Project Mix I/O with latest drivers (11/17/05), optical inputs set to ADAT, but muted/disabled in the Project Mix control panel.

Fresh install of Tiger 10.4.3, PTMP 7.0, installed 7.0CS1 update (problem occurred before AND after CS1...no apparent change).

2 x Universal Audio UAD-1 with latest software (4.1).

WaveArts TrackPlug, MasterVerb, MultiDynamics...all latest downloads of V5 code (the V7-optimized versions).

Permissions Repaired.

Preferences and Databases/Volumes folder Trashed and system rebooted per the sticky note in this forum.

Cache cleaned out (CacheOut X) at user and system level.

Spotlight shut down and disabled on all volumes.

Project @ 44.1/24, BWF files. 9 tracks of mono audio, 5 stereo Aux inputs, 5 stereo buses.

(*edit*) Buffer @ 1024, Playback engine buffering at 2 (default). UAD RTAS Wrapper at 1024 buffer.

Native Plugins: 1 instance TrackPlug, 1 instance Dither
UAD-1 Plugins: 6 plugs (1 ea. Fairchild, Pultec-Pro, Precision Multiband, Precision Limiter. 2 ea. Plate 140 Reverb).

System Usage:
CPU shows 15-20%
Disk shows 7-10%
PCI shows 0%

Yet I still get -6101 errors...sometimes nearly immediately, sometimes after 5-6 minutes of continuous play. It's almost certain to error out if I open the GUI of one of the plugins and manipulate it during play (native or UAD...doesn't seem to matter).

This CAN'T be right, can it? This is essentially unusable...it's CERTAINLY frustrating.

Go ahead...tell me what I'm missing...
