<div class="jive-rendered-content"><p>Hello .. I have a similar issue but in jboss 5.1 using ejb 3.0</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My clustered app process thousands requests but I have problems in only one node.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My bean is annotated with StrictMaxPool=100 without strictTimeout. Sometimes the max pool size is reached and the incoming requests (new bean instances creation in the pool) are blocked with <strong>Failed to acquire the pool semaphore, strictTimeout=-1</strong>. Until now it´s an application regular behavior.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>When beans creation requests  decreases my ejb blocks new instances creation =/ and <strong>Failed to acquire the pool semaphore, strictTimeout=-1 </strong>occurs all the time. It´s like the pool is still full but in JMX-CONSOLE (domain j2ee, service=EJB3) and accessing MyWorkerBean link, the AvailableCount attribute is always 0  (until in other clustered node this attribute increases and decreases normally) and worse: no bean is instantiated anymore. My pool is empty but the container can´t instatiate MyWorkerBeans anymore. Why???</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I´ll appreciate any help</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>thanks</p></div>
