Thanks Gary for your response..We have a prefetch of 10..jms.prefetchPolicy.all=10.
The thing which i am not sure ,why when one of the Consumer got the stuck in the smtp response other consumer for the same selector is stuck.(I have 5 Conusmer for the same selector). Not only the consumer got stuck the entire producer/consumer is stuck(Attachment has thread stack). See the queue stat when the entire producer/consumer is stuck. queueSize=20548 memoryPercentUsage=100 memoryUsagePortion=1.0 memoryLimit=67108864 enqueueCount=400720 dequeueCount=380172 inFlightCount=10 maxEnqueueTime=227302 minEnqueueTime=1 averageEnqueueTime=32840.18067399298 consumerCount=8 producerCount=0 isProducerFlowControl=true Is it because that particular consumer is holding the shared connection? Also i am thinking whether setting the SMTP timeout will avoid the thread getting stuck forever and it may not block the connection. Does it make sense?
