How to avoid displaying all logs

Hi

How can i avoid displaying all the logs of soap ui while i am running the soap ui functional tests as part of build/deploy automation. Due to huge number of tests and numerous number of logs will be added to console and hence heap size is not sufficient and fails the build. How can i avoid logging every step, but failed one.

I did try changing the soapui-log.xml settings and it has not effect. Below is my xml file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

The information i am seeing in the logs is (for each test)

11:48:05,631 INFO [SoapUIProTestCaseRunner] running step [stepname]
11:48:05,633 DEBUG [HttpClientSupport$SoapUIHttpClient] Attempt 1 to execute request
11:48:05,633 DEBUG [SoapUIMultiThreadedHttpConnectionManager$SoapUIDefaultClientConnection] Sending request: POST URL HTTP/1.1

11:48:05,825 INFO [SoapUIProTestCaseRunner] Assertion [XPath Match] has status VALID

How can i avoid displaying this info?
