Hi Team,
I am facing below error while working with continuous query listener. We are
receiving high number of events matching to various continuous query listeners
which result into below exception. Though task every thread s doing is really
very small (Not at all time consuming).
Any guideline on below one? Is it like thread after finishing work not going to
pool?
<gfe:cq-listener-container id="cqListenerContainer" cache="event-cache">
<gfe:listener ref="eventListener" query="SELECT * FROM /Event
WHERE entityType='A' and entitySubType IN SET ('A1','A2') and
status='PENDING'"/>
</gfe:cq-listener-container>
