Is it true if we run testCases or Suites in Parallel using groovy ,TestSuite Log will not write..???

Hi Support,

I am Using Ready API 1.3.1

When i run test suites in parallel mode in a loop ,ready api  doesnt showing any TestSuite Log.

Is it true if we run testCases or Suites in Parallel using groovy ,TestSuite Log will not write..??????

for(int testSuiteIndex=2;testSuiteIndex<testSuiteCount-1;testSuiteIndex++){
    log.info "Loop completed for    User Name: "+userName+"   Password: "+password
    log.info "Executing Test Suite: "+project.getTestSuiteAt(testSuiteIndex).getName()
    project.getTestSuiteAt(testSuiteIndex).run(null,true)
    }

Thanks,

Rajendra
