This is 2.2-stable as of Aug 18. I have posted on similar things before (running out of swap when there should be no reason), but haven't really got any ideas. What I'm seeing now is swap usage growing and growing without being able to find anything using it. last pid: 9885; load averages: 0.79, 0.72, 0.74 01:59:02 52 processes: 2 running, 48 sleeping, 2 stopped CPU states: 9.8% user, 0.0% nice, 17.3% system, 1.1% interrupt, 71.8% idle Mem: 43M Active, 11M Inact, 19M Wired, 18M Cache, 8350K Buf, 2112K Free Swap: 320M Total, 71M Used, 249M Free, 22% Inuse PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 17925 news -14 0 29740K 23424K ufslk2 237:27 8.16% 8.16% innd 3059 news 2 0 9040K 8988K select 27:33 3.17% 3.17% innfee 15153 root 2 0 676K 596K select 0:23 0.72% 0.72% sshd 9883 marcs 31 0 632K 768K RUN 0:00 2.74% 0.38% top 9885 news 33 0 252K 740K RUN 0:00 4.69% 0.23% expire 8476 news 2 0 940K 12504K sbwait 0:17 0.08% 0.08% nnrpd Then I kill pid 3059. last pid: 10457; load averages: 0.95, 0.85, 0.79 02:05:10 48 processes: 2 running, 44 sleeping, 2 stopped CPU states: 17.5% user, 0.0% nice, 14.1% system, 3.0% interrupt, 65.4% idle Mem: 52M Active, 6920K Inact, 19M Wired, 14M Cache, 8351K Buf, 1060K Free Swap: 320M Total, 36M Used, 284M Free, 11% Inuse Why is a 10 meg process freeing 35 megs of swap? I am quite sure that killing that process is what caused the problem. The process allocate and deallocates a reasonably large amount of memory over time (say... a total of a couple of gigs over the couple of days it had been running; not much more than ~10 at a time though). I haven't seen any changes in 2.2-stable recently that would fix this, but I will upgrade it when I get around to it to see...
