Ciao Eliot,
Hi Dario,
if you look at the end of the PharoDebug.log you will see:

So you have a recursive doesNotUnderstand: error and the system is running
out of memory.  The questions are where and why?  You can try and debug
this further by running the VM with --trace=259, e.g.
pharo-vm/pharo --trace=259 my image.image
This will produce lots of output, eventually ending in an endless stream
of doesNotUnderstand:'s.  So capture the first few megabytes of output (see
e.g. head(1) ($ man head))
FYI
"traceFlags is a set of flags.
 1 => print trace (if something below is selected)
 2 => trace sends
 4 => trace block activations
 8 => trace interpreter primitives
 16 => trace events (context switches, GCs, etc)
 32 => trace stack overflow
 64 => send breakpoint on implicit receiver (Newspeak VM only)
128 => check stack depth on send (simulation only)
256 => trace linked sends "
Alternatively you could use a debugger such as gdb and I can tell you how
to put a breakpoint on doesNotUnderstand:
I do this command:
*party@party001:/opt/pharolauncher/pharo-vm$ ./pharo --trace=259
/home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image*
*This is the output:*
*pthread_setschedparam failed: Operation not permitted*
*This VM uses a separate heartbeat thread to update its internal clock*
*and handle events.  For best operation, this thread should run at a*
*higher priority, however the VM was unable to change the priority.  The*
*effect is that heavily loaded systems may experience some latency*
*issues.  If this occurs, please create the appropriate configuration*
*file in /etc/security/limits.d/ as shown below:*
*cat <<END | sudo tee /etc/security/limits.d/pharo.conf*
**      hard rtprio  2*
**      soft rtprio  2*
*END*
*and report to the pharo mailing list whether this improves behaviour.*
*You will need to log out and log back in for the limits to take effect.*

Are the data you expected?
No :-).  Can you put your image and changes up anywhere I can get at them?
Or can you put them in a zip or tar archive and email them to me? I'm
curious.
