After a couple of hours the program shuts down or crashes.
The log looks like this:

2020-07-06 16:48:38: <info>  Terminating, please wait ...

but other times it closes it sais nothing.

I run with two cards:

GPU 0 PCI 07:00.0, Platform: OpenCL, Name: Radeon RX 580 Series (Ellesmere), 8192 MB available
GPU 1 PCI 08:00.0, Platform: OpenCL, Name: AMD Radeon (TM) R9 380 Series (Tonga), 4096 MB available

I saw a similar closed issue and I am currently using a script that restarts the program if it is not running.

Thanks for any help, and tell me what else you need to know.
