All, First, thank you for the many replies.
I upgraded the 970A machine from Leap 42.1 to 42.2 several weeks ago, and immediately started having problems with Google Chrome / chromium crashes, as well as a lot of "bash: fork: retry: No child processes" from shells. I tried upgrading to several different kernels (all from OBS), with similar results. I also tried playing with the IOMMU settings, both in BIOS and in the kernel parameters. The problems persisted (and still do).
Well, I was apparently mistaken about the nature of the problem. It turns out to not have been related to the hardware after all. Rather, it's a new "feature" of systemd 228. The part that I don't understand is why I wasn't seeing these problems after the systemd upgrade to 228 when the systems were running Leap 42.1. I can only conclude that there is some backward compatibility built into the systemd 228 on Leap 42.1. There appear to be several problems. 1. Basic ulimit, in particular ulimit -u. I cranked up the setting for my user in /etc/security/limits.conf (hard and soft nproc settings). 2. systemd system configuration. Edit /etc/systemd/system.conf, adjust the value for DefaultTasksMax. 3. systemd logind configuration. Edit /etc/systemd/logind.conf, adjust the value for UserTaksMax. For my system, I set these values to that seem more reasonable to me (10000), and now the systems are running properly.
