How to stop the Sahi logging feature in Appvance IQ.

While I am running sahi/designer based vusers in Appvance IQ, sahi logs are taking up lot of disk space (sometimes 100 GB in 3 to 4 days).
How can we disable the traffic logs that are written to this folder?
/AIQ/sahi/userdata/logs/traffic

Solution:
Kill all java process, Start sahi dashboard alone in the below given path.
Please try disabling the traffic logs by launching sahi dashboard(/AIQ/sahi/userdata/bin/start_dashboard.bat).

Restart Appvance IQ.
