List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 02 Aug 2018 01:51:21 -0000 The patch to report OOMA information did its job, very tersely. The console reported v_free_count: 5439, v_inactive_count: 1 Aug 1 18:08:25 www kernel: pid 93301 (c++), uid 0, was killed: out of swap space The entire buildworld.log and gstat output are at http://www.zefox.net/~fbsd/rpi3/swaptests/r336877M/ It appears that at 18:08:21 a write to the USB swap device took 530.5 ms, next top was killed and ten seconds later c++ was killed, _after_ da0b was no longer busy. This buildworld stopped a quite a bit earlier than usual; most of the time the buildworld.log file is close to 20 MB at the time OOMA acts. In this case it was around 13 MB. Not clear if that's of significance. If somebody would indicate whether this result is informative, and any possible improvements to the test, I'd be most grateful. Thanks for reading, bob prohaska
