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?

Something like this:

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