Both binaries and compiled from sources Massa node fails to start with the error below:

What's the spec of the computer that produce this bug and what's the version of the binaries tested ?

[aoudiamoncef]

I added the node spec in the issue above

[AurelienFT]

What's the OS ?

[aoudiamoncef]

Ubuntu 20.04.01 and 20.04.02

[aoudiamoncef]

We have multiple people report this error, even with a decent node specs

This could happen at startup or after 10h or 10min of running.

@sydhds we need your help for this time

[sydhds]

Looks like an error related to assembly code emitted by the wasmer compiler (singlepass) and AVX.

@aoudiamoncef can we have more info about the processor used?

[aoudiamoncef]

Netcup VPS details

It seems that they are running on AMD processors for vserver

Will be fixed in TEST.23 with the update of wasmer : https://github.com/massalabs/massa-sc-runtime/pull/249
