How to stop running a test script?

[Vladimir Tsygankov]

Hello, friends!
 
Could you please answer me is any tool in Jmeter to stop my script when
it is running under Jmeter without 
GUI (it is important!).
I want to stop running after I get a response about Exception. My test
script has lots of 
threads and if I get response with java exception and don't break
sending new requests the server is down.
Assertions can test responses and allow to analyse requests with string
like "Exception:" but how to stop running my script?
 
Thanks in advance,
Vladimir
