    Socket error caused by remote host?

    D Chen Newbie

      Hello,

      Can anyone tell me how to fix this error or have ideas about this error?

      2006-06-06 10:19:41,442 ERROR [org.apache.tomcat.util.net.PoolTcpEndpoint] Socket error caused by remote host /129.1.2.9
      java.net.SocketException: Invalid argument

          We are having the same stack getting thrown to our logs.

          We are running:
          -Java 1.5.1_06 on
          -Solaris 8 with
          -Apache 2.0.54 and
          -Mod_jk 2.10 load balancing in front of several
          -JBoss 4.0.2 servers.

          The only helpful information I could find was: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6378870

          This gives a plausible explaination for a root cause. However I'm not sure why our embedded Tomcat would be unable to respond to the inbound requests. Does anyone have any thoughts on what to dig further on? Is there more monitoring we could put in place?

          I can't tell if this is a configuration issue in our environment or if this is a bug in our code.

          Thanks in advance for any help

              I see a similar ERROR logged from time to time:

              2008-03-20 14:14:06 -0700 org.apache.tomcat.util.net.PoolTcpEndpoint

              Guess this is due to clients aborting the connection, so it's nothing I need to be concerned about. But how do I suppress these ERROR messages? I've added the following to the log4j.conf but no luck:

              <category name="org.apache.tomcat.util.net.PoolTcpEndpoint">
               <priority value="SEVERE"/>
              </category>

                Perhaps "FATAL" instead of "SEVERE". "SEVERE" is a java.util.logging level.

                  Oh... Thanks!

                    This is a SUN bug[1].

                    "The issue here is not that the socket has been closed but rather than the peer has reset the connection. On Solaris the setsockopt(3SOCKET) call returns EINVAL when the connection is reset.

                      Strange: I'm seeing this error on Linux as well.
