Wehave deployed a Wicket application that runs fine, but every once in a
while I see a stacktrace in my Tomcat logs that says
ERROR - DefaultExceptionMapper :mapExpectedExceptions.144 - Connection
lost, give up responding.
Which appears to be caused by:
java.net.SocketException: Connection reset by peer: socket write error
This often occurs when no users are logged into the application. I've
searched for an answer to this, but haven't been able to find anything
useful. A lot of information about this error if you are trying to do a file
transfer, but nothing related to my current situation.
I'd appreciate it if anyone could suggest a way of tracking this down. The
stacktrace isn't too helpful and none of the classes listed in it are
classes that we developed, they are all framework classes (Tomcat, Wicket.
Spring,etc.) I've included the whole stacktrace below.
Could this be someone attempting to hack in, or something that happens when
a browser is closed?
