Mahout LDA issue: small word probability in each topic

Hi All: I have successfully compiled the Mahout 0.9 on Hadoop and submit the LDA CVB model, most of the parameters are set to default values and the --maxIter is set to 25. After we got the model, we found that the word probability in each topic is quite small, most of them are about 0.1
