             Summary: TCPConnection allocates 1.5G after reading incorrect header in the connection
                 Key: JGRP-2472
                 URL: https://issues.redhat.com/browse/JGRP-2472
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.6.13
            Reporter: Pavel Molchanov
            Assignee: Bela Ban

We are using FILE_PING JGroups functionality with Artemis servers.

Periodically (very rate) we see that TCPConnection allocates 1650814049 bytes in the receiving buffer.

This is similar to the https://issues.redhat.com/browse/JGRP-1117 issue.

This issue is happening periodically and it's clearly visible in the memory dumps from Artemis servers.

Screen-shots of the dumps are attached.

Can TCPConnection be protected from the incorrect input?

https://github.com/belaban/JGroups/blob/JGroups-3.6.13.Final/src/org/jgroups/blocks/cs/TcpConnection.java

Something like this:

{code}
int len=in.readInt();  
if(len==1650814049) throw InvalidStateException(); 
{code}
