> During our test, the network between JBoss and Oracle has some problem for a
> while. At that time, one JR thread which holding Global ISM lock is doing
> socket read with Oracle. Unfortunately, this blocking socket read doesn't
> return anymore. Meanwhile, some other threads are warting for the global ISM
> lock. As a result, many threads are blocked.
> Although we only hit it once, but it is really a serious problem. To
> workarount it, we have to restart our application server. To our custom, it
> is not acceptable.
