<div class="jive-rendered-content"><p>i changed the implementation little bit so that i have completely removed the SingtonScheduleBean and moved the timer to SLSBean. from functionlaity wise it is doing exactly what i was expected in terms of firing timeout by container (timerservice) and calling aviable SLSB instances from the pool as i limited to 7. in the ejb-interseptors-aop.xml using StrictMaxPool=7 </p><p>but server throws below exception( this make sense because i ristricted slsbs to be 7) and if the TimerService expires it has to wait for the SLSBs from completing their current process to get the 8th one. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>how to stop these ERRORS to be thrown in logs. </p><p style="min-height: 8pt; height: 8pt; padding:
