broken pipe error messages thrown by tomcat -- how to suppress?

[Clive]

We are getting quite a few "broken pipe" messages in the error log
thrown when users click Cancel or Reload before the page they are
viewing completes its load.

I know these errors are benign, so I don't want them written to the
log: it fills up quite quickly. If there are real errors in the log,
I may miss them because of the "noise" of the broken pipe messages.

Is there a way to configure Tomcat to suppress the error?

Thanks,
Clive.
