DO NOT REPLY [Bug 50072] New: Blank responses
https://issues.apache.org/bugzilla/show_bug.cgi?id=50072
Summary: Blank responses
Product: Tomcat 6
Version: 6.0.24
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: petr@creactive.cz

Tcp dump log with blank and normal responses.
We are facing problem with empty file response from server, after upgrading
from Apache 6.0.20 to any higher version. Approx 20% generated responses went
ok, 80% responses were empty files without any error log. Types of files was
XML, HTML pages - with no diffrence. Files were requested by browsers, PHP
scripts (XML) from different client servers.
I started to log all the requests on top of doGet() method and all the normal
responses logged correctly. Incorrect requests never get to aplication, empty
files had no log.
There was no diffrence when server had load on the resources were free. We use
"org.apache.coyote.http11.Http11NioProtocol", requests were sent with GET
method. I attach TCPdump from one of the client-side servers - what they see.
After downgrade back to 6.0.20 the problem dissapeared, so we are kind of
locked there.

Thanks for the feedback. Good to know the problem I found was the same one you
were seeing.
Keeping open until the patch has been applied to 6.0.x

Thanks for the additional traces and analysis. The analysis is particularly
helpful. I tracked the problem down to a long standing issue in the NIO
connector where request lines sent in more that one packet are likely to be
mis-read. The simplest way to reproduce this is to use telnet.
I have applied a fix for this issue to 7.0.x and it will be included in 7.0.4
onwards.
I have proposed a port of the same fix for 6.0.x (patch attached).

There haven't been any similar reports and 6.0.24 was released almost 9 months
ago. Either the application is triggering a rare code-path in Tomcat which is
hitting a bug or the application is sending invalid requests that Tomcat is now
being stricter in how it is handling them.
I tried to read the attached trace in Wireshark but a dump of the text output
from tcpdump is not easily imported. Looking through the text output I see some
oddities (e.g. Host headers in a HTTP 1.0 request) but nothing that jumps out
as obviously malformed.
Please provide a complete tcpdump trace of 5 to 10 requests in pcap format that
demonstrates this issue.
Also, note there is no need to edit the file to obscure any host names, IP
addresses etc. since they are all present in the hex data in the attached file.
You might also like to try running Tomcat with the BIO connector to see if the
problem remains.

This problem has tomcat 6.0.24 and all next releases. I tested it now with
version 6.0.29 and php on one of our client servers where the problem was
detected before. Problem is with http 1.0 requests from php (fopen,
simplexml_load_file functions) and NIO connector. Same script works fine with
BIO connector. Http 1.1 requests (curl, fsockopen php functions) works fine
with both connectors. I attach bio.log and nio.log tcpdump logs. Top +- 10
requests are from simplexml_load_file and next are curl and fsockopen.
