Hello.
I'm getting Connection closed by foreign host, when there is more than 200
clients to activemq.
I use activemq-5.2.0 as a stomp server.

[root@db bin]# java -version
java version "1.6.0_0"
IcedTea6 1.3.1 (6b12-Fedora-10) Runtime Environment (build 1.6.0_0-b12)
OpenJDK 64-Bit Server VM (build 1.6.0_0-b12, mixed mode)

Nothing changed in default config.

What is the reason and how do I fix it?

The log says:
