Inbound Channel Adapter Poller

[uter]

Hi,
I have an Inbound Channel Adapter which read datas from a Database every 100 ms:

<int:inbound-channel-adapter auto-startup="false"
ref="dbAdpater"
method="getNextMessagesToProcess" channel="processChannel" >

<intoller task-executor="dbThreadPoolExecutor">
<int:interval-trigger interval="100" />
<int:transactional transaction-manager="transactionManager"
propagation="REQUIRED" />
</intoller>
</int:inbound-channel-adapter>

<int:thread-pool-task-executor id="dbThreadPoolExecutor" max-size="10"/>

With this configuration, I expected to have up to 10 threads running in parrallel where each thread are running within is own Transaction. I'm right?

When I let this running, I get following exception:

[task-scheduler-2] ERROR org.springframework.integration.handler.LoggingHan dler - org.springframework.core.task.TaskRejectedExceptio n: Executor [java.util.concurrent.ThreadPoolExecutor@1e67a57] did not accept task: org.springframework.integration.util.ErrorHandling TaskExecutor$1@113f917; nested exception is java.util.concurrent.RejectedExecutionException

Can you tell what's wrong?

Are you defining a default poller anywhere else? Maybe with rejection-policy="ABORT"?

A long shot but this might cause this if the poll is slow since the default behaviour of your dbThreadPoolExecutor when it has more than ten tasks will be caller runs.
