It's funny that a packet with bela in it would cause somebody's program to crash. View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4136855#4136855 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4136855

My immediate thought it is there is some packet being received that has a bad size value, which is why a 1.6GB buffer might have been allocated. Maybe you could patch the code that allocates that array to throw an exception when a certain size limit is reached? I'd also try to run tcpdump and

I'll tell our infrastructure to try and grab that information next time they get the opportunity which may be a while since it they have no way to grab the dumps unless the problem happens to freeze the server which is usually just crashes. Looking at the stack traces I'm not sure what would

I have some more info. If found the line of code that is allocating the 1.6gb byte[]. BasicConnectionTable.run():577 | 575: len=in.readInt(); | 576: if(len buf.length) | 577: buf=new byte[len]; | So you were correct it

Actually I lied the packet's contents are: [98, 101, 108, 97, 17, 2, 4, 10, 108, 34, 34, 0, 0, -30, -112] the first 4 bytes == bela 10.108.34.34 is my server's IP address I don't know what the rest is. View the original post :
