Cant able to see errors Pentaho 4.4 errors in Logging Panel

I am using pentaho 4.4. After executing the transformation at the end i am seeing the below lines

ERROR (version 4.4.0-stable, build 17588 from 2012-11-21 16.02.21 by buildguy) : Errors detected!
ERROR (version 4.4.0-stable, build 17588 from 2012-11-21 16.02.21 by buildguy) : Errors detected!


But the error cause is not showing. In Step Metric table the 'Active' column is displaying as stopped for all the steps

Please help me out in identifying the cause of the error.
