https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263062 --- Comment #11 from Max Khon <fjoe@FreeBSD.org> --- With the help from glebius@, kib@ and afedorov@ the root cause has been identified to be this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D= 269823 The patch (https://reviews.freebsd.org/D38898) resolves the issue with inpcb leak in 13-STABLE (and with user processes stuck on close(2) in 14-CURRENT). The symptom (without the patch) is as follows: --- top -HSP --- last pid: 2699; load averages: 4.35, 3.16, 1.41=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 up 0+00:02:53 03:35:34 807 threads: 8 running, 773 sleeping, 26 waiting CPU 0: 0.0% user, 0.0% nice, 99.2% system, 0.0% interrupt, 0.8% idle CPU 1: 47.5% user, 0.0% nice, 2.8% system, 0.3% interrupt, 49.4% idle CPU 2: 46.9% user, 0.0% nice, 2.9% system, 0.3% interrupt, 49.9% idle CPU 3: 47.2% user, 0.0% nice, 2.6% system, 0.5% interrupt, 49.7% idle Mem: 4098M Active, 1130M Inact, 955M Wired, 483M Buf, 1522M Free Swap: 3676M Total, 3676M Free PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND 5 root -16 - 0B 16K CPU0 0 2:51 100.00% rand_harvestq 11 root 155 ki31 0B 64K RUN 1 1:27 73.97% idle{idl= e: cpu1} 11 root 155 ki31 0B 64K RUN 2 1:30 71.97% idle{idl= e: cpu2} 11 root 155 ki31 0B 64K CPU3 3 1:29 69.97% idle{idl= e: cpu3} 2665 sentry 79 0 338M 143M CPU2 2 0:03 23.97% python3.9 910 kafka 21 0 5150M 443M uwait 1 0:07 1.95% java{C2 CompilerThread0} 1246 sentry 20 0 241M 148M uwait 3 0:00 0.98% python3.9{rdk:main} 0 root -16 - 0B 640K swapin 3 690:21 0.00% kernel{swapper} 1204 www 78 0 24M 13M RUN 0 0:07 0.00% nginx ... --- cut here --- --=20 You are receiving this mail because: You are the assignee for the bug.=
