All, I recently upgraded my 12-STABLE system to the latest, and now my swap subsystems aren't working. I deliberately set up a 40GB partition for swap, and when I do 'top -t' I am only seeing 7906M total. When using synth, it shows swap usage of < 2%, but then it gives the 'out of swap' complaint and tosses all my users out into neverland. My /boot/loader.conf has: kern.maxproc=75000 kern.maxswzone=17200000 ... but those are no longer effective. What has changed, and what do I need to do to rectify this? -- Don Wilde **************************************************** * What is the Internet of Things but a system * * of systems including humans? * ****************************************************

And if so, where? What does pstat -s say?> When using synth, it shows swap usage of < 2%, but then it gives the > 'out of swap' complaint and tosses all my users out into neverland.Unless this also causes kernel messages to that effect, this, too, could be an issue with synth.

It was sitting at 0.0 - 1% swap. Perking right along. Looked away to another bit of work and it has blyecch'd again. Rebooted, starting it again. It does seem to start over from where it crashed, which is good. I'm not in any way saying that this is a bad tool, just trying to figure out why it crashes even with all the resources I've given it. Building math/openblas and devel/llvm90 simultaneously, so it's obvious what put it over the top! Sigh... barfed again, but at least this time it marked those as failed and started on new ports. I guess if I keep repeating the process it'll get through them all. :D -- Don Wilde **************************************************** * What is the Internet of Things but a system * * of systems including humans? * ****************************************************
