"Too many open files" exception when hotdeployment set to true, after loading
configurationContext multiple times
-----------------------------------------------------------------------------------------------------------------
Key: AXIS2-2899
URL: https://issues.apache.org/jira/browse/AXIS2-2899
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: deployment
Affects Versions: 1.2
Environment: Windows XP,
Sun JRE 1.4.2 or IBM JRE 1.4.2,
running JUnit test from within Eclipse 3.2.2
Reporter: Greg Lee-Shoy
Priority: Minor
-When configuration context is loaded about 400 times using
createConfigurationContextFromFileSystem( ), and hotdeployment is set to true,
the following error occurs: java.io.IOException: Too many open files.
-if hotdeployment is set to false, this error does not occur even after loading
configurationContext 100,000 times
-if there is a check in getURLsForAllJars() in
org.apache.axis2.deployment.util.Utils to see if a URL has file protocol (and
not creating a temp file if it does) the threshold is raised to 2826 times,
after which an OutOfMemoryError occurs.
The JUnit test is:
import org.apache.axis2.context.ConfigurationContext;
import org.apache.axis2.context.ConfigurationContextFactory;
import junit.framework.TestCase;
public class LoadConfigFromFileTest extends TestCase {
public LoadConfigFromFileTest(String name)
{
super(name);
}
public void testLoadConfig1000Times()
{
try
{
ConfigurationContext configContext = null;
String axis2Conf = "C:\\Java\\axis2\\conf\\axis2.xml";
String repoDir = "C:\\Java\\axis2";
for( int i = 0; i < 1000; i++)
{
System.out.println("Iteration " + i);
configContext =
ConfigurationContextFactory.createConfigurationContextFromFileSystem(
repoDir, axis2Conf);
configContext = null;
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
