[jboss-user] [EJB3] - Re: Failed to acquire the pool semaphore in empty pool

Garry Dias [http://community.jboss.org/people/garrydias] created the discussion "Re: Failed to acquire the pool semaphore in empty pool" To view the discussion, visit: http://community.jboss.org/message/625559#625559 -------------------------------------------------------------- Let me explain better... It´s my stateless bean: @Clustered @Stateless(name = "MyWorkerBean") @Pool(value = PoolDefaults.POOL_IMPLEMENTATION_STRICTMAX, maxSize = 30) public class MyWorkerBean implements WorkerInterface {      public void sleep(boolean flag) throws Exception      {           Thread.sleep(60000);      } } To stress this bean, I´m using a JMeter test case with 100 concurrent threads. Each thread perform a ejb lookUp for MyWorkerBean. Each instance looked up performs a call to sleep() method. So, the first 30 lookups will perform and 70 will "Fail to aquire pool semaphore, strictTimeout=-1". Now, I have 30 bean instances filling the pool for 60 seconds and the MBean for MyWorkerBean in jmx-console marks AvailableCount as 30. After 60 seconds all 30 instances perform succesfully and I run 100 more jmeter threads, but this time all lookups blows with "Fail to aquire pool semaphore, strictTimeout=-1" and the MBean for MyWorkerBean in jmx-console marks AvailableCount as 0. PS: the look up is performed by: org.springframework.beans.factory.BeanFactory.getBean("MyWorkerBean") h5. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/625559#625559] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
