This is clearly an OS or JVM problem - nothing really to do with JMeter, except of course it is triggering the issue. Maybe the OS is running low on resources, and this is causing the name resolution to fail. Try searching for the error message and see if anyone else has got the issue. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
