Plot stop using SSD

[Simfiz]

Hi guys, have a problem with parallel ploting
While creating 2 plots in parallel mode, one of them stop use SSD and working at all, but it use other resources (CPU and RAM).
It happens not always, but often.
During the plotting nothing except chia and hpool is running.
I don't get any errors in debug log and plotting log.

Your telling the system to assign 12 threads to each plot and your system only has 12.
Try using just 2 threads.
