Solution:

Install JBOSS native libraries and set LD_LIBRARY_PATH

1) Download  jboss-eap-native-5.0.1-RHEL5-i386.zip for Linux.

2) Extract the zip file to temporary location and move the native folder to jboss-eap-5.0.1 directory (one level above jboss home directory).

The structure looks like this.

jboss-eap-5.0.1

   |__jboss

   |__native

3) Update install account's profile (/home/jbossadm/.bash_profile)

Add this line to the .bash_profile 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JBOSS_HOME/../native/lib

4) Exit from Unix shell 

5) Restart JBOSS server
