Lots of TIME_WAIT connections for webserver

I'm running an E420 as a webserver with another e420 running as the oracle
DB sever. They're connected by 100 MBit ethernet, and the webserver has an
additional 100 MBit ethernet card as its public interface. The webserver
is using openssl...

Anyway, here's the output of the following command:

netstat -an | awk '{print $7}' | sort | uniq -c | sed '1d;/[-]/d'

  51 ESTABLISHED
   3 FIN_WAIT_2
   7 IDLE
  35 LISTEN
   1 Remote
   2 Rwind
 437 TIME_WAIT

Is that a lot of time_wait connections? It's quite a few more than this
server's predecessor. Over the course of writing this email the number of
time_waits has been fluctuating between 180-360. Is this a matter I should
be concerned with?
