occasional error on build machines(AccessViolationException)

Hi,

My guess is that problem is related to usage of multi threading in the test or in the code under test.
We have fixed few issues regarding multi threading in the Isolator since version 5.4.2.0.
Can you try to install the latest version (6.0.4) and see if it solves the problem?

hi, thanks for the reply. i have to talk it over with my boss. probably we have to try your solution

Hi again,

we've switched onto Isolator 6.0.4. unfortunately we had problem yesterday. another System.AccessViolationException in unexpected place and time. we run test again and everything's ok. what to do now, what would you suggest?

Hi,

Do the same tests always fail? Do they ever fail if run alone, or only when run with all tests?

Can you post the code for one of the failing tests?

Thanks,
Doron

we run all tests and the error occurs randomly for methods, projects...

here is the letest lucky one:
public override void StartService()
{
try
{
XXXTracer.Write("XXXX StartService.");
if (ServiceState == ServiceState.Started)
{
throw new ServiceAlreadyStartedException(Resources.ApplicationInfoAlreadyStarted);
}

ScanApplications();
ServiceState = ServiceState.Started;

}
catch (Exception ex)
{
ServiceState = ServiceState.Malfunction;
throw new Exception(Resources.ApplicationInfoStartingFailed, ex);
}
}

...
XXXTracer just uses TraceSource object and trace info
...
ServiceState is a simple property setter
....
Isolate.NonPublic.WhenCalled(service, "ScanApplications").IgnoreCall();
....
exception:
System.AccessViolationException : Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
