--Sig_rQp_J0S92vixBVoING5W7ix Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable There was a "request" for Tor related problem reports a while ago, I couldn't find the message again, but I believe it was posted here. Last week I installed: FreeBSD tor.fabiankeil.de 6.1-RELEASE-p2 FreeBSD 6.1-RELEASE-p2 #0: Fri Jun 23 20:06:57 CEST 2006 fk@fabiankeil.de:/usr/obj/usr/src/sys/BIGSLEEP i386. At the moment it is only acting as Tor node <http://serifos.eecs.harvard.edu/cgi-bin/desc.pl?q=3Dzwiebelsuppe>; tor-devel (maintainer CC'd) is running jailed in a Geli image, ntpd, named, cron and sshd are running in the host system and that's about it. No mail or web server and nearly no traffic besides the one caused by Tor. I started Tor Friday night and had to reset the box three times since then. The server just suddenly stops responding, the logs stop as well, therefore I assume it either panics or hangs. I only have remote access, a serial console is available, but it becomes unresponsive as well. I didn't configure DDB yet, so maybe that is to be expected? cron creates some stats every five minutes, a few minutes before a hang this morning the load was: last pid: 7996; load averages: 0.40, 0.37, 0.36 up 0+18:38:25 05:5= 5:02 83 processes: 2 running, 66 sleeping, 15 waiting CPU states: 21.3% user, 0.0% nice, 17.8% system, 20.2% interrupt, 40.7% id= le Mem: 100M Active, 157M Inact, 102M Wired, 12K Cache, 60M Buf, 134M Free Swap: 1024M Total, 1024M Free PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 11 root 1 171 52 0K 8K RUN 857:30 53.61% idle 12 root 1 -44 -163 0K 8K WAIT 45:22 6.54% swi1: net 23 root 1 -68 -187 0K 8K WAIT 14:48 2.83% irq12: fxp0= fxp1 7973 root 1 96 0 2264K 1544K RUN 0:00 0.51% top 13 root 1 -32 -151 0K 8K WAIT 5:49 0.10% swi4: clock= sio 33 root 1 171 52 0K 8K pgzero 0:02 0.10% pagezero 3 root 1 -8 0 0K 8K - 0:16 0.05% g_up 1586 _tor 14 20 0 99M 97912K kserel 188:36 0.00% tor 15 root 1 -16 0 0K 8K - 1:01 0.00% yarrow 1443 root 1 -8 0 0K 8K geli:w 0:49 0.00% g_eli[0] md0 4 root 1 -8 0 0K 8K - 0:21 0.00% g_down 35 root 1 20 0 0K 8K syncer 0:17 0.00% syncer 1439 root 1 -8 0 0K 8K mdwait 0:13 0.00% md0 24 root 1 -64 -183 0K 8K WAIT 0:08 0.00% irq14: ata0 2 root 1 -8 0 0K 8K - 0:07 0.00% g_event 42 root 1 -16 0 0K 8K - 0:06 0.00% schedcpu 453 root 1 96 0 2920K 1752K select 0:05 0.00% ntpd 256 _pflogd 1 -58 0 1548K 1216K bpf 0:05 0.00% pflog pfctls -si: Status: Enabled for 0 days 18:37:52 Debug: Urgent Hostid: 0x1ec3da6b Interface Stats for fxp0 IPv4 IPv6 Bytes In 25077859159 0 Bytes Out 27498863362 0 Packets In Passed 36192760 0 Blocked 32213 0 Packets Out Passed 36871432 0 Blocked 265 0 State Table Total Rate current entries 5290 =20 searches 73567507 1096.8/s inserts 600068 8.9/s removals 594778 8.9/s Counters match 752600 11.2/s bad-offset 0 0.0/s fragment 102 0.0/s short 0 0.0/s normalize 2 0.0/s memory 68 0.0/s bad-timestamp 0 0.0/s congestion 0 0.0/s ip-option 0 0.0/s proto-cksum 0 0.0/s state-mismatch 12655 0.2/s state-insert 0 0.0/s state-limit 0 0.0/s src-limit 2 0.0/s synproxy Today's traffic graph: <http://www.fabiankeil.de/blog-surrogat/2006/06/27/tor.fabiankeil.de-dritte= r-ausfall-24-stunden-durchsatz-statistik-595x337.png> (The hang around 14:00 happened while I was logged in doing a buildworld) At the moment I'm building RELENG_6 with DDB to see if it changes anything and if I can get a core dump, but so far the problem seems to be similar to: http://www.freebsd.org/cgi/query-pr.cgi?pr=3D95180 (closed) and <http://freebsd.rambler.ru/bsdmail/freebsd-questions_2006/msg08692.html= >. Is anyone on this list running a Tor node on FreeBSD 6.1-RELEASE or later with similar or higher load?
