Connection reset errors

Hi folks,
  I'm noticing a bunch of errors in the logs today. Any ideas what would
cause this / what I should look for? They occur on different pages, at
different times, but they're all basically the same "Connection reset"
error. Looking in my postgres log file shows no errors there.
I'm running Tomcat 3.3 / RedHat 7.3 (kernel-2.4.18-10) / Postgres 7.2.1
jar tvf pgjdbc2.jar (the latest verson I found about 4 weeks ago) gives:
