"Size limit on Remote EJB Calls"

--------------------------------------------------------------
I have a SLSB that I invoke remotely and there appears to be a limit on how large the
argument I can pass in a method call is. I'm using EAP 6.0.1 (jboss as 7.1.2 Final)
and deploying my ejb as part of an ear. My client runs in a separete JVM and uses
jboss-ejb-client 1.0.5.Final.
EJB3 interface:
public String ingest(NATLog[] values);
EJB3 impl:
@Override
public String ingest(NATLog[] values) {
//do something
}
NATLog is a simple POJO with 11 String member variables. The total size of one of these
fully populated is about 300 bytes.
When I use an array up to about 150 NATLog objects, the EJB call works fine. When I pass
in an array of 200 NATLog objects, the EJB call just hangs. And when I finally kill the
client via ctrl-c, I get the following error message in the server's console.

Caused by: an exception which occurred:

1. Is there a size limit for the data passed in via remote EJB3 calls?
2. Are there any settings I can do in JBoss to tune the behavior with regard to EJB
calls?
Thanks,
Justin
