Along with what Scott mentioned, we would also need to know the version you are using.
Our release notes for R 14.1 has some fixes to the Explore and Correlate features.
1080794 | DE364476 | Inbound notifications get stuck when CA Identity Manager Task Persistence is cleanup before processing the notifications. | The inbound event processing task fails to find the correct environment ID for the parent event that is deleted, resulting in a null pointer exception. |

if you are not already on CP5, then upgrade to CP8 which has the code to fix this, and this does not resolve the issue, you will need to create a support ticket for us to investigate further.
