this would be your hint
java.lang.OutOfMemoryError
so yes, running out of memory would crash your server. what you can do is
1. upgrade to 1.4.2_14
2. add "-XX:+HeapDumpOnOutOfMemoryError" to your JAVA_OPTS
this will produce a .hprof file containing your memory dump, you can then
analyze the dump using www.yourkit.com

Hi,
I'm running Tomcat 5.0.28 with JDK 1.4.2_10, and I can see in catalina.out a
lot of :
GRAVE: Remote Host /xxx.xxx.xxx.x SocketException: Invalid argument
Jul 2, 2007 2:16:18 AM org.apache.tomcat.util.net.TcpWorkerThread runIt
When I have around 50 messages like this one, I can see this message :
GRAVE: Remote Host /xxx.xxx.xxx.x SocketException: Invalid argument
Jul 2, 2007 2:20:24 AM org.apache.coyote.http11.Http11Processor process
GRAVE: Error processing request
java.lang.OutOfMemoryError
After this message my servers crash.
That IP is a loadbalancer, and when I watch for TCP trace, I can see that the
loadbalancer send RST to my server when the
exception appear, but I also see that each RST received by the server doesn't
match with the exception.
I found some people having the same problem but no solutions.
Do you know if it is a known Tomcat issue? I haven't found it in the bug
database.
Any help is greatly appreciated
Best regards,
Boris
