Issue with the console

My application developed using websphere 6.1 is using MQs.I need to refresh data after every 1 min.The application is running successfully and I am getting the output properly in the logs. But in the console I am getting the output for the first few minutes.After that the output is not getting appended in the console.But the logs are still giving me the correct output. I am using RAD.
Console settings- Fixed width console:not selected, Maximum character width:160 Limit console output:not selected ,Display tab width:8, Show when the program writes to standard out:selected, Show when the program writes to standard error:selected.
Please guide to resolve this issue.
