invoke-vmscript exitcode -3

Hi

I am running a powershell script that invoke running of exe inside a VM. It work very strange. In some cases it work fine with exitcode 0 and in some cases I get exitcode -3.

The exitcode -3 can happen to the same VM it work fine just few hours before. Restarting the target VM doesn't solve this.

I didn't find any documentation about invoke-VMscript exit codes and what they mean.

Will appreciate any help

Thanks
