Hey pplz : ) Checked on SER and there was a popups prompting me to stop the projects and decrease threads, as SER did not have enough memory.
I have had the auto decrease on CPU usage above 87% checked since I started with SER.
Also have checked Auto decrease threads on memory usable above 4000 Mb.
I've run three times this threads number without issue in the past, many many times.
Also, nothing else running, 26132 MB free. 32 GB system
I chose to ignore, and keep the projects going, then got a custom GSA error box.
