If there is a high request count, the client will get a 503 error. I have two apaches (accessed by round robin dns) and two tomcats. So if one of them fails, the other one should handle the requests. Unfortunately this doesn't work, both fail at the same time :-( The apache error log shows the following: [error] ajp_read_header: ajp_ilink_receive failed [error] (120006)APR does not understand this error code: proxy: send body failed to (null) (x.x.x.x) [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header The tomcat logs contain broken pipe errors and IOExceptions, but I found in #38489 that this is the expected behaviour. org.apache.jk.core.MsgContext action WARNING: Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.jk.common.ChannelSocket.send(ChannelSocket.java:531) Aug 17, 2007 1:12:44 PM org.apache.jk.common.ChannelSocket processConnection WARNING: processCallbacks status 2 java.io.IOException at org.apache.jk.common.JkInputStream.receive(JkInputStream.java:190) at org.apache.jk.common.JkInputStream.doRead(JkInputStream.java:164) at org.apache.coyote.Request.doRead(Request.java:418) at org.apache.catalina.connector.InputBuffer.realReadBytes(InputBuffer.java:284 ) at org.apache.tomcat.util.buf.ByteChunk.substract(ByteChunk.java:371) at org.apache.catalina.connector.InputBuffer.readByte(InputBuffer.java:293) at org.apache.catalina.connector.CoyoteInputStream.read(CoyoteInputStream.java: 104) The issue #36495 deals with similar problems. So I tried to set MaxClients to 512 and keepalive=On (without success).
