Hello! I'm a golang newbie, so could anyone help me with strange memory allocation by my program.
What I have from "runtime/pprof": > Entering interactive mode (type "help" for commands) > (pprof) top > 25987.89MB of 26181.92MB total (99.26%) > Dropped 59 nodes (cum <= 130.91MB) > flat flat% sum% cum cum% > 23691.69MB 90.49% 90.49% 24513.87MB 93.63% calc/reference.FetchCost > 1536.02MB 5.87% 96.36% 1562.52MB 5.97% calc/reference.FetchRevenue > 760.17MB 2.90% 99.26% 760.17MB 2.90% calc/reference.kvsCost > 0 0% 99.26% 26181.92MB 100% runtime.goexit > 0 0% 99.26% 24513.87MB 93.63% calc/reference.Update.func1 > 0 0% 99.26% 1562.52MB 5.97% calc/reference.Update.func2 But, atop/htop/top/ps shows me the follow: # ps aux | head -n 1; ps aux | grep calc > USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND > root 69439 129 96.0 64702588 63118748 ? Ssl 00:10 806:18 > /opt/calc/bin/calc --config /opt/calc/conf/prod.yml And sometimes comes in OOM killer and kill my program: Nov 20 06:29:34 mcalc-stage kernel: Out of memory: Kill process 61018 > (calc) score 941 or sacrifice child > Nov 20 06:29:34 mcalc-stage kernel: Killed process 61018 (calc) > total-vm:65761252kB, anon-rss:64416000kB, file-rss:128kB > Nov 20 06:29:34 mcalc-stage kernel: mcalc: page allocation failure: > order:0, mode:0x2015a So, the main question why pprof show me that my program eats only 25Gb memory, while the atop/htop/top/ps shows me real situation. -- Петровский Александр / Alexander Petrovsky, Skype: askjuise Phone: +7 914 8 820 815 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
