I'm using tomcat 4.1.30. How do I interpret a message like this and what can I do about it?

Buffer overflow
Dear all, I've written a little servlet that gets some binairy data from my database and shows it to the user. Basicly an image servlet. Here's some code: // Set the response mime type response.setContentType(uiElement.getType()); // Get outputstream ServletOutputStream output = response.getOutputStream(); // Write the byte array byte[] data = output.write(uiElement.getByteValue()); output.flush(); output.close(); Now I see the following errors in my application.log: Jan 30, 2003 2:06:35 PM org.apache.jk.common.MsgAjp cpBytes SEVERE: Buffer overflow: buffer.len=8192 pos=29 data=30988 And this in my catalina.log: 00 00 00 00 04 00 c8 00 | ..?. | Do I have to increase that buffer size (how?) or should I place .flush() every 8k?

Strange behaviour of Tomcat like a buffer overflow
Hi! My application hehaves very strange in an unpredicable way. In both apache and tomcat logfiles I see requests that seem to arrive in a random order. The Tomcat logfile even shows HTML output of my servlets. At times in the apache access log the request with HTTP GET parameters is shown correct, but in tomcats access log the request is logged altered with some garbage behind the ?. My system config: httpd-2.0.40.tar.gz jakarta-tomcat-4.1.17.tar.gz j2sdk-1_4_1_01-fcs-linux-i586.rpm Here are a few lines from the Tomcat access log: 192.168.1.254 - - [18/Dec/2002:01:09:10 1000] POST /avsSignon/servlet/signonMember HTTP/1.1 200 - r report/tit - - [18/Dec/2002:01:09:11 1000] GET /avsSignon/member/clubFront.jsp HTTP/1.1 302 - ster Club/TI - - [18/Dec/2002:01:09:11 1000] GET /avsSignon/member/clubFront-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:11 1000] GET /avsSignon/signon.css HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:12 1000] POST /avsSignon/servlet/signonMember?ily to a new locatio HTTP/1.1 302 - ountry/TITLE - - [18/Dec/2002:01:09:12 1000] GET /avsSignon/member/usrCountry-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:12 1000] GET /avsSignon/signon.css HTTP/1.1 304 - r report/tit - - [18/Dec/2002:01:09:14 1000] POST /avsSignon/servlet/signonMember HTTP/1.1 302 - ype of paymen - - [18/Dec/2002:01:09:14 1000] GET /avsSignon/member/usrPayment-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:14 1000] GET /avsSignon/signon.css HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:14 1000] GET /avsSignon/images/YikesterLogo.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:14 1000] GET /avsSignon/images/visa.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:14 1000] GET /avsSignon/images/mastercard.gif HTTP/1.1 304 - r report/tit - - [18/Dec/2002:01:09:15 1000] POST /avsSignon/servlet/signonMember HTTP/1.1 302 - ent by credit - - [18/Dec/2002:01:09:15 1000] GET /avsSignon/member/usrCreditCard-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:15 1000] GET /avsSignon/signon.css HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:15 1000] GET /avsSignon/images/YikesterLogo.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:15 1000] GET /avsSignon/images/visa.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:15 1000] GET /avsSignon/images/mastercard.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:16 1000] POST /avsSignon/servlet/signonMember HTTP/1.1 200 - r report/tit - - [18/Dec/2002:01:09:18 1000] GET /avsSignon/member/clubFront.jsp HTTP/1.1 302 - ster Club/TI - - [18/Dec/2002:01:09:18 1000] GET /avsSignon/member/clubFront-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:18 1000] GET /avsSignon/signon.css HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:19 1000] POST /avsSignon/servlet/signonMember?ily to a new locatio HTTP/1.1 302 - ountry/TITLE - - [18/Dec/2002:01:09:19 1000] GET /avsSignon/member/usrCountry-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:19 1000] GET /avsSignon/signon.css HTTP/1.1 304 - r report/tit - - [18/Dec/2002:01:09:19 1000] POST /avsSignon/servlet/signonMember HTTP/1.1 302 - ype of paymen - - [18/Dec/2002:01:09:19 1000] GET /avsSignon/member/usrPayment-en.jsp HTTP/1.1 200 - 192.168.1.254 - - [18/Dec/2002:01:09:20 1000] GET /avsSignon/signon.css HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:20 1000] GET /avsSignon/images/YikesterLogo.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:20 1000] GET /avsSignon/images/visa.gif HTTP/1.1 304 - 192.168.1.254 - - [18/Dec/2002:01:09:20 1000] GET /avsSignon/images/mastercard.gif HTTP/1.1 304 - Any help is greatly appreciated.
