RHEL 6 and WebSphere Message Broker

I installed WMB 7.0.0.2 on RHEL 6, which is supported according to this link:

http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27017129

I installed under root

Then I switched to mqm via "su mqm"

After installation, I started mqsiprofile with the ". ./mqsiprofile" command,
and I created a broker:

bash-4.1$ ./mqsicreatebroker LQM2 -q LQM2
WebSphere MQ queue manager created.

This was successful, then I tried to start the broker:

bash-4.1$ ./mqsistart LQM2

I opened the /var/log/messages file and found the following:
