Description

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.
