1. Tomcat 4.0.3 is pretty old and unsupported. The last version in the 4.x series is 4.1.36.
2. Trying to google "checkHead site:mail-archives.apache.org" shows some mentions of similar issues in the year 2002, e.g. (note: The bugzilla server name has changed, but bug ids are the same) http://issues.apache.org/bugzilla/show_bug.cgi?id=10331 Citing from there: "Your extra code does not matter -- your code is still violating the servlet spec restrictions on accessing the response object from one thread in another thread. Your expectation that this is ever going to work is incorrect." http://issues.apache.org/bugzilla/show_bug.cgi?id=8039 Citing from there: "This problem has already been fixed in 4.0.4 Beta." It looks like nobody has observed this problem in the last 5 years, thus it has been fixed. You need to upgrade to get rid of the issue. Good luck.
