Apache-Tomcat comm fails streaming objects of certain predictble sizes
Summary: Apache-Tomcat comm fails streaming objects of certain
predictble sizes
Product: Tomcat 4
Version: 4.1.29
Platform: All
OS/Version: All
Status: NEW
Severity: Critical
Priority: Other
Component: Connector:Coyote JK 2
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: cap@pcweenie.com
CC: cap@pcweenie.com
------------------
Description:
------------------
On certain sized objects, the communication between Apache and Tomcat via the
JK2 connector is failing. If the object streamed to the servlet is 8187 or 8188
bytes (and any size a factor of 8186 bytes larger than those two sizes [e.g.,
16373 & 16374, 24559 & 24560, etc.]), the servlet gets an java.io.EOFException.
I wrote a simple client application, RemoteRequest, and servlet,
TestModJK2Servlet demonstrate this problem. It appears to be a bug in either
the connector or in Tomcat, but is probably the former. I believe 8186 is the
size of the AJP frame within a 8192 byte UDP packet, so there's probably a snag
in something like buffer rotation logic or something similar.
============================================
Configuration:
============================================
I would be happy to zip up and send the test application and servlet and
supporting classes I used to produce this bug. With the configuration below, it
is consistently reproducable.
RemoteRequest is an application that makes a remote request to a servlet
running in a Tomcat container via an Apache web server. For this test,
RemoteRequest builds a byte array object of size 1 to size N. The size of the
object the byte array occupies (which seems to be 27 bytes + the size of the
byte array itself) is computed. It is increased by one on each request. Both
the RemoteRequest application and the TestModJK2Servlet log which requests
they are able to successfully and/or unsuccessfully receive. The RemoteRequest
application, the Apache http server, and the Tomcat servers (two servers - load
balanced with equal weights and with session affinity), all reside on separate
physical servers. The versions and configurations of these follow:
============================================
Apache 2:
============================================
Version 2.0.47 Downloaded from the Jakarta project. Configured with the
following command:
JDK version 1.4.2_01 (from binary download)
./configure --prefix=/usr/local/apache2ssl --with-mpm=worker --enable-so --
enable-ssl=shared --enable-proxy=shared --enable-proxy-ftp=shared --enable-
proxy-http=shared --enable-proxy-connect=shared --enable-cgi --enable-
rewrite=shared --enable-http
Running on a Sun Netra t1 (UltraSPARC-IIi 440MHz), 512 MB memory
OS: Solaris 2.7 (with recommended patches)
============================================
Tomcat:
============================================
Tomcat version 4.1.29 (from binary download)
JDK version 1.4.2_02 (from binary download)
J2EE SDK 1.3.1_01 (from binary download)
TestModJK2Servlet installed at /TestModJK2Servlet
Running on a Dell server with dual 2.0GHz Xeon processors, 2048 MB memory.
OS: RedHat Linux 9.0
============================================
Tomcat Jakarta Connector:
============================================
Compiled the native2 version for Apache 2.0 using the source downloaded from:
http://apache.oregonstate.edu/jakarta/tomcat-4/v4.1.29/src/jakarta-tomcat-
connectors-4.1.29-src.tar.gz
Running on the Apache2 system above.
============================================
Client Application (RemoteRequest):
============================================
A simple client that makes HTTP request like an applet does.
JDK version 1.4.2_02 (from binary download)
J2EE SDK 1.3.1_01 (from binary download)
Running on a Sun SunFire 280R server with dual 900MHz UltraSparc-III
processors, 2048 MB memory.
OS: Solaris 2.8
