[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.

Subject: [hobbit] Large number of TIME_WAITs
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?
