Stuck threads in weblogic

[ravikr02]

Hi

We are facing below error frequently in our appliocation:

"[STUCK] ExecuteThread: '13' for queue: 'weblogic.kernel.Default (self-tuning)'" id=2247 idx=0x264 tid=1248 prio=1 alive, waiting, native_blocked, daemon

Here is the set-up:
1. A jdbc message store backed queue
2. A particular request puts about 10-15 messages continuously to the queue.
3. We have jdbc batched all the transactions.

Could you please help me with this error?

Could you please provide more information as to what triggers this error? In other words what happens in your application to force this error. We can't fix it unless it is reproducible and i want to get some idea how to reproduce it.

Thanks Oleg for your reply.

Our application generates about 50 different events.
We use the following configuration for each event:
1. Queue Channel for buffering messages, backed by a jdbc message store

	<jdbc:message-store id="TESTMsgStore" data-source="GlobalMsgStoreDS" region="TEST1" />
	<si:channel id="TESTQ">
		<si:queue message-store="TESTMsgStore" />
	</si:channel>

2. A pub-sub channel

	<si:publish-subscribe-channel id="TESTPubSubChnl" >
		<si:interceptors>
			<ref bean="GlobalMsgInterceptor" />
		</si:interceptors>
	</si:publish-subscribe-channel>
	<si:service-activator input-channel="TESTPubSubChnl" ref="TestSubscriber" method="processMsg" />

3. A chain to connect the queue and the pubsub channel:

	<si:chain input-channel="TESTQ" output-channel="TESTPubSubChnl">
		<si:poller fixed-rate="60000" max-messages-per-poll="1" task-executor="">
			<si:transactional transaction-manager="txManager" />
		</si:poller>
		<si:filter ref="GlobalMsgSelector" />
	</si:chain>
