Hello all,

I'm having constant crashes that appear to be VE Pro-related (crash log is 500 pages).

I'm up to 26 Projects (Instances, some call them), plus three more for the satellite PCs that are feeding samples. Plus a couple of Kontakt, UVI, Dune 3, and so on.

My question is -- how many VE Pro Projects in a single VE Pro server are manageable? How many is "too many" in your system?

Overall setup:

  • DAW is Digital Performer 11.22
  • VE Pro 7 Server 7.2.1516
  • Kontakt 5, 6 and 7; DUNE 3, East-West PLAY v.
  • Three separate satellite PCs running VE Pro (same version) divided into Perc, Strings, Brass&Winds&Choirs
  • Computer is a Mac Pro with over 300 GB of RAM and 16 processors.

Here's a portion of the crash log (from pages 1-2):

Hi Paul, 

Thank you for writing back.  I emailed the crash log to the support email.

In the mean time, I also lowered the number of threads available to each instance (project) to four.  It had been at 16 (of 32).  For the time being that has helped somewhat.

It happens when the rig is under heavy strain -- full orchestra, choir, dozens of synths, and loads of percussion.

Thank you,
