Restart Silktest Agent at Runtime

Last few months, I faced one issue and solved it by restarting silktest Agent.
Problem
We have a silktest suite for our Excel AddIn. It is developed by DotNet Framework. Silktest DotNet extension goes off after running 75-200 tests. Also facing this issue differently for both Excel 2003 and Excel 2007. Already I raised one post 'Application not responding" for this.

Solution:
Later selected cases are executed fine, If I close silktest agent and re-run few cases. I am able to figure out, where/when it is not able to identify. Then I tried to restart the agent in that machine, while scripts are executing continuously.
