Hi Davide,

Taking a look at the dump, I���d say it looks like a memory corruption.

It crashes when running the GC, but very probably because the heap was already corrupt.

Does this happen often in your setup?

Hi Sven,
It has not happened today. I also use a lot of OsProcess, but I don't know
if it is related to it.
Cheers
Davide

I can't see anything networking, HTTP or Zinc related in the dump.
It looks like something went wrong during garbage collection.
I suppose this is not a repeatable case, is it ?

Hi guys,
I'm working on Pharo 8 on BigSur 
(Pharo 8.0.0 Build information:
Pharo-8.0.0+build.1128.sha.9f6475d88dda7d83acdeeda794df35d304cf620d (64
Bit))

Yesterday after an http call to my zinc server the image crashed.
Can you please take a look to the dump file and tell me what happened?

It would be worth so much to me, thank you

The file is here: https://pastebin.com/SrE6gcCv
