How to recover from a VM crash

horrido
I have an emergency. One of my JRMPC teams says they can't open the image. They get a long error message that begins with:

Exception code: C0000005
Exception addr: 000000000041FB6B

Crashed in the VM thread


They didn't do a backup, so have they lost their code? Is there any way to recover?

Thanks,
Richard

Hi,

I don’t know if they will be able to use the image again but they can take a new image, open Epicea (Tools -> code changes).

In Epicea they can locate the Epicea logs from their old image (in /pharo-local/ombu-files IIRC) and then they can replay their changes.

Hi,

Regardless of the crash, the code should have been preserved through the .changes file.
They can attempt to replace the image file with a clean one, and apply those changes
(a window should open on startup, otherwise it's accessible through left click in world -> code changes)
