I assume that you already sent a crash log to VSL and they could not help.
Just a question is VEP crashing when the instances of an already opened VEP project with all instances you need loaded connects to the DAW or when you first open e.g. Cubase with coupled instances included and then let it open VEP and create the required instances? This second way of working might create a fresh version of you VEP project eliminating all legacy issues. It works with simple single output instruments but I am not sure if it also works with multiple outputs per instrument.
In most cases debugging VEP issues remains try and error. Especially if one is no expert in how different aspects of the whole combination of VEP, plugins and DAW influence memory usage. Based on what you write it does seem a memory overload maybe just on a specific area or core. According to some demos on Youtube surprisingly Cubase seems to be better in using all performance and efficiency cores than Apple’s own Logic.
Some small observations I made. There seems to be a memory peak higher than the sum of all loaded instances when one or more instruments start playing especially for the first time in a VEP session even if all VEP instances seem to have been loaded and show activity after connecting That might be the point the crash occurs.
Anther point is that instrument focus button in VEP. The circle with the cross. It makes the VEP view jump around from one instrument plugin to another based if it starts playing I think. I am not sure but if this might also give a small memory increase. I usually put it off.
Another point to try, have you tried putting the OT and VSL instruments on different ports in VEP? The crash might occur if OT tries to use a memory area already used by a VSL instrument or vice versa. Maybe using different ports might avoid this.
I have shared a few logs already, but no luck. I think because it's likely one of the plugins or channels. I have OT and VSL running on separate ports.
I had MIDI activity focus, I have switched it off now and see how it goes.
VEP crashes either when loading the server project by itself (80% of the times), when opening an empty session and loading a Cubase/Logic project (coupled) (100% of the times), and if I manage to get over that point when I start playing it crashes again (50% probability). So all in all, after 20 mins of loading samples I have like a 10% probability that it will actually play anything.
I hope I am starting to narrow it down to one particular instance with OT SINE plugins, and the one with the biggest consumption of RAM. I don't know yet if it's the routing (sometimes I see that the aux outputs from channels having plugins get disconnected from the plugin channel itself) or if perhaps it's one of the SINE instances loading too many samples in RAM (I have all Ben Wallfisch Strings loading 6 mic positions in a single instance of 28 GB).
