Setup:
Main Mac - running Digital Performer 9.1 and with an orchestral template running 12 instances of the VEP MAS stub plug-in (latest version 5.4 14074)
2 Secondary Windows 10 PC's - running VEP Server 64-bit with lots of instances of Kontakt. I put the VEP metaframe file into the startup items, so that when I turn the Windows PC's on, they automatically launch VEP Server and start loading all their samples. The only plug-in in use within VEP is Kontakt 5 (latest version) and that is running as a 64-bit VST.
The problem:
4 out of 5 times, this all works perfectly.
1 out of 5 times, when I boot up the Windows PC's, VEP Server 64-bit launches, and the main window comes up (the smaller window that normally has the list of all my instances), and I see the overlay with the spinning ball that says "Loading data, please wait..." -- however -- it never loads. None of my instances ever show up, and even if I wait hours (!!) it never budges.
I can always fix it by quitting VEP Server and relaunching it, and it always loads fine on the next launch. Or I can reboot the computer, which will then auto-launch the VEP metaframe and, as stated above, 4/5 of the time it launches fine.
But why does it hang 1 out of 5 times??
How can I troubleshoot this?
