http://issues.apache.org/bugzilla/show_bug.cgi?id=30551 [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|REOPENED |RESOLVED Resolution| |WORKSFORME ------- Additional Comments From [EMAIL PROTECTED] 2005-04-13 09:48 ------- Again, I've tested this on XPsp2 with all patches applied with Tomcats 5.0.30, 5.5.9, 4.1.31 and 4.1.29, and jk1.2.10. (Both IIS and Tomcats are on the same host). As many of you reported it is happening only on XP with sp1 or sp2, in some sittuations, so I expect that you have some sort of third-party antivirus software installed. Also the error message: [Mon Apr 04 09:02:40 2005] [0212:3740] [error] read::jk_isapi_plugin.c (584): ReadClient failed with 0000274c Means: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. So the simple reason can be that used OS is workstation level (XP) and imposes the limit on number of concurrent connections to IIS For workstations this is 10 IIRC. For example if I run on my XP: ab -n 1000 -c 5 -p tmp.txt http://localhost/examples/servl et/SessionExample Everything works fine (5 concurrent connections) But If I use ab -n 1000 -c 10 -p tmp.txt http://localhost/examples/servl et/SessionExample I receive: 2005.04.13 09:45:23 org.apache.jk.common.ChannelSocket processConnection SEVERE: Error, processing connection java.net.SocketException: Software caused connection abort: recv failed at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:129) at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) at java.io.BufferedInputStream.read1(BufferedInputStream.java:256) at java.io.BufferedInputStream.read(BufferedInputStream.java:313) at org.apache.jk.common.ChannelSocket.read(ChannelSocket.java:548) at org.apache.jk.common.ChannelSocket.receive(ChannelSocket.java:486) at org.apache.jk.common.ChannelSocket.processConnection (ChannelSocket.ja va:603) at org.apache.jk.common.SocketConnection.runIt(ChannelSocket.java:786) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run (ThreadP ool.java:666) at java.lang.Thread.run(Thread.java:595) So this means that IIS refused connection. I would suggest that you guys use any Server version of Windows OS if high load is required. Please do not reopen this case, because it has nothing to do with JK, because it's the IIS limitation.
