I think my node deadlocked, or, if it didn't it was very busy doing nothing. There were around 12 connections that didn't have blocked data. I watched it for a minute, and none of the network connections moved any. This is with 6207 on Linux 2.4.21. I'm on a 400 MHz CPU. I've found that most CPU overload can be mitigated with outputBandwidthLimit=4000, so I am using that. I tried getting a backtrace with kill -QUIT `cat freenet.pid`, but that didn't do anything (maybe I didn't wait long enough). When my node isn't so hosed, it does give data.
If it was deadlocked, this is bad, freenet either needs to read inbound data first, or close those connections, if it doesn't plan on reading the data. It feels like freenet went to write data, tried, wrote 0, went on the the next one to write, wrote 0, and so on, in a tight busy loop, hoping that the situation would clear. It will never clear, beacuse the thing it is writting to is never gonna read, because he is also deadlocked just like I am. The only way out, is to time out a connection after 60 seconds, or read first. Also, if there is such a tight busy loop, could you put a sleep (1) in it every 1000 time around the loop, just so that I can have a little CPU left, so maybe the backtrace will work. $ netstat -a -n | grep EST tcp 429 0 myhost:13302 130.13.65.134:1517 ESTABLISHED tcp 76726 0 myhost:13302 81.227.199.250:3417 ESTABLISHED tcp 65482 0 myhost:4298 217.215.133.88:54272 ESTABLISHED tcp 0 14162 myhost:3335 134.147.115.107:3260 ESTABLISHED tcp 0 24278 myhost:3281 213.107.75.168:18001 ESTABLISHED tcp 0 13348 myhost:3583 140.180.158.97:44748 ESTABLISHED tcp 77208 0 myhost:13302 81.50.179.250:30621 ESTABLISHED tcp 0 14368 myhost:3519 82.36.35.68:12151 ESTABLISHED tcp 77205 0 myhost:13302 213.152.37.170:46866 ESTABLISHED tcp 428 0 myhost:13302 130.13.65.134:2847 ESTABLISHED tcp 76802 0 myhost:13302 212.174.25.228:3824 ESTABLISHED tcp 0 13620 myhost:3270 24.129.111.17:22524 ESTABLISHED tcp 0 21605 myhost:3310 66.68.42.206:55132 ESTABLISHED tcp 430 0 myhost:13302 130.13.65.134:1273 ESTABLISHED tcp 0 600 myhost:3254 213.46.231.136:11901 ESTABLISHED tcp 0 13229 myhost:3255 68.55.184.122:16918 ESTABLISHED tcp 42172 0 myhost:13302 68.161.57.111:4058 ESTABLISHED tcp 0 13890 myhost:3278 12.209.102.138:28352 ESTABLISHED tcp 76746 0 myhost:13302 81.227.199.250:3420 ESTABLISHED tcp 942 0 myhost:13302 212.185.238.111:4406 ESTABLISHED tcp 429 0 myhost:13302 130.13.65.134:3194 ESTABLISHED tcp 0 13472 myhost:3764 80.142.178.167:34264 ESTABLISHED tcp 77018 0 myhost:13302 24.90.214.91:3509 ESTABLISHED tcp 76334 13544 myhost:3650 24.103.100.162:61281 ESTABLISHED tcp 76869 0 myhost:13302 65.60.197.71:64365 ESTABLISHED tcp 0 14374 myhost:3269 152.7.44.211:5997 ESTABLISHED tcp 429 0 myhost:13302 130.13.65.134:3904 ESTABLISHED tcp 26319 0 myhost:13302 211.121.18.208:32993 ESTABLISHED tcp 11762 0 myhost:13302 24.217.72.178:64873 ESTABLISHED tcp 0 14259 myhost:3405 12.212.225.11:47254 ESTABLISHED tcp 76734 0 myhost:13302 81.227.199.250:3415 ESTABLISHED tcp 944 0 myhost:13302 80.242.40.246:63412 ESTABLISHED tcp 10758 0 myhost:13302 142.161.83.17:4356 ESTABLISHED $ vmstat 600 procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 4 0 0 9100 4816 4932 30456 0 0 5 11 178 444 63 2 35 1 0 0 9996 5644 5008 32124 0 0 7 14 160 473 65 2 33 0 0 0 10124 4744 5008 29024 0 1 4 16 187 543 65 3 32 4 0 0 10380 5524 4812 25824 0 1 3 15 184 583 63 4 34 2 0 0 8872 22772 4936 27976 0 0 4 15 166 386 74 3 23 8 0 0 8872 8732 4964 30064 0 0 0 14 166 449 64 2 34 4 0 0 8872 6072 4972 30808 0 0 0 13 175 431 58 2 40 6 0 0 8872 5824 4972 30360 0 0 0 5 145 310 70 1 29 3 0 0 8872 5460 4972 30360 0 0 0 0 137 281 100 0 0 3 0 0 8872 5096 4972 30360 0 0 0 0 138 342 99 1 0 3 0 0 8872 4992 4972 30360 0 0 0 0 131 344 100 0 0 3 0 0 8872 4896 4972 30388 0 0 0 0 147 342 99 1 0 3 0 0 8872 4892 4972 30388 0 0 0 0 137 345 100 0 0 3 0 0 8872 4816 4972 30388 0 0 0 0 131 342 100 0 0 Here, you can see that I shouldn't have been overloaded, 20-40% free, and then, we just locked. We can see data moving in and out before it fell over, and after, no data. _______________________________________________ Devl mailing list [EMAIL PROTECTED] http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/devl
