intermittent SocketException on startup tomcat 5.5.28 and under JBOSS 4.2.3GA
Good Morning Excuse for my poor english I have a strange error that occours on startup and after some minutes this cause the block of my appliction, only stop webserver from lot minutes or restart server sometime resolve the problem. But often the problem persist. In Short: I have a web appliction deployed initially under tomcat 5.5.28 (with jre- 1_5_0_22 and SO win2003 Server 32 bit) that sometimes cause specially on startup the follow error: 17-apr-2010 7.00.49 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket GRAVE: Endpoint [SSL: ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=443]] ignored exception: java.net.SocketException: socket closed java.net.SocketException: socket closed at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(Unknown Source) at java.net.ServerSocket.implAccept(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLServerSocketImpl.accept(Unknown Source) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.acceptSocket (JSSESocketFactory.java:117) at org.apache.tomcat.util.net.PoolTcpEndpoint.acceptSocket(PoolTcpEndpoint. java:408) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt (LeaderFollowerWorkerThread.java:71) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool. java:689) at java.lang.Thread.run(Unknown Source) 17-apr-2010 7.01.10 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket AVVERTENZA: Reinitializing ServerSocket 17-apr-2010 7.52.33 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket GRAVE: Endpoint [SSL: ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=443]] ignored exception: java.net.SocketException: socket closed java.net.SocketException: socket closed at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(Unknown Source) at java.net.ServerSocket.implAccept(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLServerSocketImpl.accept(Unknown Source) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.acceptSocket (JSSESocketFactory.java:117) at org.apache.tomcat.util.net.PoolTcpEndpoint.acceptSocket(PoolTcpEndpoint. java:408) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt (LeaderFollowerWorkerThread.java:71) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool. java:689) at java.lang.Thread.run(Unknown Source) 17-apr-2010 7.52.54 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket AVVERTENZA: Reinitializing ServerSocket 17-apr-2010 7.52.55 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket GRAVE: Endpoint [SSL: ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=443]] ignored exception: java.net.SocketException: socket closed java.net.SocketException: socket closed at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(Unknown Source) at java.net.ServerSocket.implAccept(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLServerSocketImpl.accept(Unknown Source) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.acceptSocket (JSSESocketFactory.java:117) at org.apache.tomcat.util.net.PoolTcpEndpoint.acceptSocket(PoolTcpEndpoint. java:408) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt (LeaderFollowerWorkerThread.java:71) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool. java:689) at java.lang.Thread.run(Unknown Source) 17-apr-2010 7.53.16 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket AVVERTENZA: Reinitializing ServerSocket 17-apr-2010 7.53.17 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket GRAVE: Endpoint [SSL: ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=443]] ignored exception: java.net.SocketException: socket closed java.net.SocketException: socket closed at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(Unknown Source) at java.net.ServerSocket.implAccept(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLServerSocketImpl.accept(Unknown Source) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.acceptSocket (JSSESocketFactory.java:117) at org.apache.tomcat.util.net.PoolTcpEndpoint.acceptSocket(PoolTcpEndpoint. java:408) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt (LeaderFollowerWorkerThread.java:71) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool. java:689) at java.lang.Thread.run(Unknown Source) 17-apr-2010 7.53.38 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket AVVERTENZA: Reinitializing ServerSocket 17-apr-2010 7.53.39 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket GRAVE: Endpoint [SSL: ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=443]] ignored exception: java.net.SocketException: socket closed java.net.SocketException: socket closed at java.net.PlainSocketImpl.socketAccept(Native Method) . in tomcat server.xml i have configured 2 connector: one su port 80 and other on port 443, The connectors configuration is: Connector port="80" maxHttpHeaderSize="8192"

Thanks for suggestion. But i have win2008 with dual quad core processor, 4GB ram. The CPU usage is to 5% and ram is used to the 75% when error occours. What block the reload time of page (in presence of error all is more slow the IE page often is white)?

Thanks The question started in http://mail-archives.apache.org/mod_mbox/tomcat-users/201005.mbox/thread?3 on same thread. Now i have reduce the number of user (about 50 user simultanely) on a win2003 ED quad processor with 8GB bram (I have tomcat 5.5.28, jdk.1.6.16, IIS (with certificate instaled) on port 80 that redirect request from port 80 to 8080 tomcat connector server. Besides https request are directly managed from second connector, on port 443 of tomcat.) So the error referred, sometime occours. In particular i have noted that this error rise when a lot user make login in the application ( in a few second). Probably this may be depend from a lot tcp/ip connection, but, this using netstat -na not appear. May be i must increase the number on maxTcpConnection on win2003 server and/or reduce tcpDelay. Please give me a help to resolve the problem. What tool i can use for investigate who cause socket close.

Thanks for replay. I'm sorry I have missed e-mail regard server .xml with romment removed. so I attached this file. regard i think that a mistake the correct form is in the file. "SIT" is name of my application. I don't able to match timestamp of error whith a request because i don't know how to trace all request in tomcat conaitner. How can do it?

Yes i have one application SIT under C:\tomcat5\webapps\SIT In the same dir i have olso a rar (not war) file SIT.rar that is a rar compressed file of SIT. Only file log that i have other tomcat log is standard IIS log. How i can improve verbosity of tomcat so i can match timestamp of error on other relevant information ? bye.

R: Re: R: Re: intermittent SocketException on startup tomcat 5.5.28 and under JBOSS 4.2.3GA
HI for right knowledge I am able, now, to reproduce the socket error that occur. In my lan i have a proxy server (192.168.0.254) so on server win2003 on which i have tomcat5.5.28 (IP: 192..168.0.100) if i don't use in IE proxy configuration all it's ok but if i configure proxy server and port : if i don't specify a server IP(tomcat server) as exception (i.e example 192.168.0.100) i have the error on socket , meanwhile if i specy this IP i don't have a error. Now how can i configure Tomcat so that it is insensible to proxy configuration on IE namely tomcat don't have a error on socket if i have or don't have proxy configuration? I already use Remote Address Filter on server.xml but this isn't useful.
