Ciao,

Hi,

The problem seems to come from: "no room in eden for allocateSmallNewSpaceSlots:format:classIndex:"
Eden is a part of the heap where new objects are allocated.
Basically, it appears that Pharo cannot create objects any more.
You can get information about gc and eden space here:

Could you try to run your image in headless mode to see if it starts?
ex: 

I would try to start your image with a bigger size for the eden.
Clément recommends to do: Smalltalk vm parameterAt: 45 put: (Smalltalk vm parameterAt: 44) * 4.
but it means you need an image that is started …

You can also set it as an argument to the VM: --eden <size>[mk]

You could try with —eden 15207744 for example:
~/Documents/Pharo/vms/70-x64/Pharo.app/Contents/MacOS/Pharo --eden 15207744 ~/Documents/Pharo/images/Pharo\ 7.0\ -\ 64bit\ \(development\ version\)/Pharo\ 7.0\ -\ 64bit\ \(development\ version\).image 

After copy the pharoLauncher entry with the error into 
Pharo7.0-64DTRDevErr entry

i do this:

/opt/pharolauncher/pharo-vm$ ./pharo --eden 15207744 /home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image

the shell report:

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.
For more information please see
...........r3732#linux
Errore di segmentazione (core dump creato)

Any idea  about it?

So you have a segmentation fault. It means the image tries to access a memory address outside the memory range of its process.
using gdb on the core dump could help to have more clues: https://www.cprogramming.com/debugging/segfaults.html

Tomorrow i investigate about it.

Do you also have a segmentation fault if you run the image without the eden parameter?

No without eden parameter the system report the basic error

no room in eden for allocateSmallNewSpaceSlots:format:classIndex:

The ***** message required some action ?

this message is just a warning. If you want to avoid it, just execute this as root:
cat <<END | sudo tee /etc/security/limits.d/pharo.conf
*      hard rtprio  2
*      soft rtprio  2
END

P.S. I have to conclude that there is no solution?

For now, it is too early to have a conclusion because we do not know what caused the crash.
As Eliot said, it could be useful to get the crash.dmp file and the PharoDebug.log file.

The  crash.dmp  is not create.

( If i right do the command to create it :

From pharoLauncher i launch the corrupt image some time,
the  shell report the issue, but don't create the crash.dmp file).


For PharoDebug.log  i'm not in office, I'll check tomorrow.

Thanks,
Dario
