[hobbit] Large number of TIME_WAITs

What OS? Some operating systems allow network connections to hang around a bit after disconnection. On Solaris you can set a parameter to reduce the timeout period. Hobbit could trigger this because each client connects to the server, sends a data blast, and then disconnects.

I noticed something strange on my Hobbit server, though I'm not

sure if it's a problem or not. There are about 140 TIME_WAITs from the local IP of the Hobbit server, and about 30 TIME_WAITs from localhost, all using port 1984. They look something like this:

0      0 1.2.3.4:42389         1.2.3.4:1984          TIME_WAIT
0      0 1.2.3.4:42394         1.2.3.4:1984          TIME_WAIT
0      0 1.2.3.4:42399         1.2.3.4:1984          TIME_WAIT
0      0 1.2.3.4:42396         1.2.3.4:1984          TIME_WAIT
0      0 1.2.3.4:42397         1.2.3.4:1984          TIME_WAIT

0      0 127.0.0.1:42310             127.0.0.1:1984

TIME_WAIT 0 0 127.0.0.1:42309 127.0.0.1:1984 TIME_WAIT 0 0 127.0.0.1:42315 127.0.0.1:1984 TIME_WAIT 0 0 127.0.0.1:42322 127.0.0.1:1984 TIME_WAIT 0 0 127.0.0.1:42320 127.0.0.1:1984 TIME_WAIT

There are also a few on various other ports:
0      0 127.0.0.1:42246             127.0.0.1:29021

TIME_WAIT 0 0 127.0.0.1:42301 127.0.0.1:29023 TIME_WAIT 0 0 127.0.0.1:42362 127.0.0.1:29017 TIME_WAIT 0 0 127.0.0.1:29030 127.0.0.1:42380 TIME_WAIT 0 0 127.0.0.1:42348 127.0.0.1:29019 TIME_WAIT

Any idea why there should be so many of them, particularly on

the localhost address? And any idea if this looks abnormal or not?
