Hi 'm having an issue when I try to make the synthesis of my project, in concrete in when I do the harden in the user project example. The error is as follows
Copy code

I check the logs but is the same info that the one presented here. Any idea how to find the cause of that?

Please take a look at "dmesg" to see whether it was an out-of-memory that killed the process

Thanks, yes I look the dmesg and is an out of memory problem. I will increase the RAM and try again.
