Created attachment 256505 [details] syslog of crash The entire system hung up, I restarted and checked the syslog and found this error and some bizarre stuff. I also got pop up errors from various applications saying they could not create threads, or ran out of memory. htop though told me I had 13+ GB free of memory.
