(some very random debugging - not sure I can reproduce)
Just had the loading error followed by Supercollider Fail error after ;restart. At this point cpu was reporting like 97% so I checked top and saw
410 we 20 0 103156 33480 7732 S 100.5 3.5 4:45.27 sclang
which is sclang using 100.5%+ of the cpu.
After this I did a stop.sh and start.sh and things seemed to be working again, but then I tried stopping the systemctl services and got this;
Cannot read socket fd = 5 err = Success
CheckRes error
JackSocketClientChannel read fail
Cannot read socket fd = 10 err = Success
CheckRes error
JackSocketClientChannel read fail
restarting the systemctl services threw this (repeating):
JackLinuxFutex::Signal name = jack_sem.1000_default_system already deallocated!!
JackLinuxFutex::Signal name = jack_sem.1000_default_freewheel already deallocated!!
ResumeRefNum error
I was apparently on an older release on this Pi so some of this could be related to softcut changes - I’d loaded mangl and glut and had a few errors that tipped me off to norns not being updated
I’ll keep an eye out for any repeats of this weirdness
