2 years ago I am also seeing the same problem with Ardour: two instances of the same Camomile LV2 plugin will work fine, but having two different Camomile plugins causes Ardour to hang.
Environment
OS: Debian 11
Architecture: amd64
DAW: Ardour 6.7.0
Camomile version: v1.0.8-beta10Some debug output from Ardour
I had a project in Ardour which already used an instance of AlmondOrgan (LV2). That works well. When I add an instance of the Castafiore effect (also LV2) to an audio track, Ardour freezes/hangs. At the same time, Ardour's terminal output is filled with thousands of repetitions of this message:
JUCE Assertion failure in juce_MessageManager.cpp:310Basic investigation: what assertion is failing?
The error message refers to this part of Juce/modules/juce_events/messages/juce_MessageManager.cpp:
bool MessageManager::Lock::tryAcquire (bool lockIsMandatory) const noexcept
{
auto* mm = MessageManager::instance;
if (mm == nullptr)
{
jassertfalse;
return false;
}
...
}I don't know the JUCE code well, but the following around line 420 is suspicious. It loops over (a wrapper method of) the tryAcquire method.
bool MessageManagerLock::attemptLock (Thread* threadToCheck, ThreadPoolJob* jobToCheck)
{
...
// tryEnter may have a spurious abort (return false) so keep checking the condition
while ((threadToCheck == nullptr || ! threadToCheck->threadShouldExit())
&& (jobToCheck == nullptr || ! jobToCheck->shouldExit()))
{
if (mmLock.tryEnter())
break;
}
...
}Any ideas or comments would be appreciated because I'd like to get this bug fixed!

(in the plugin by distrho called ildaeli when I enable 'run in bridge mode' I am able to load multiple instances. Also in reaper when I run carla as dedicated process I am able to load multiple instances)
Whether or not the same issue is present in vst3 idk because those don't load at all but I'll make a separate issue for that. It happens in Carla and reaper, both latest versions on 32 bit linux mint 19. it happens wirh all plugins generated through camomile. Multiple instances of the same plugin does not cause this issue. Carla freezes before it logs anything about the second instance, but here's a log anyway:
