Normally I don't use any swap space but after a huge pkg upgrade three days ago I've suffered a problem with the entire swap partition filling up and the system freezing on about 4 occasions. I suspect that this might be due to a bug in plasma5-plasma-workspace which was upgraded from version 5.14.5.1 to 5.15.0 because it now appears to require 128GB virtual memory curlew:/home/mike% top -o size last pid: 1738; load averages: 0.22, 0.32, 0.21 up 0+00:12:44 16:11:28 144 processes: 1 running, 142 sleeping, 1 zombie CPU 0: 0.8% user, 0.0% nice, 0.4% system, 0.4% interrupt, 98.4% idle CPU 1: 0.8% user, 0.0% nice, 0.4% system, 0.0% interrupt, 98.8% idle CPU 2: 1.6% user, 0.0% nice, 1.2% system, 0.0% interrupt, 97.3% idle CPU 3: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 1653M Active, 470M Inact, 2104M Wired, 40K Buf, 11G Free ARC: 1264M Total, 430M MFU, 801M MRU, 4703K Anon, 4920K Header, 24M Other 742M Compressed, 1059M Uncompressed, 1.43:1 Ratio Swap: 8192M Total, 8192M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 1272 mike 13 20 0 128G 210M select 3 0:05 0.01% plasmashe The corresponding value for SIZE before the upgrade was 293M. The problem is only sporadic, I can run for several hours with no swap being used (as in the above output from top) and then it suddenly fills up. -- Mike Clarke
