Domino HTTP process hangs/crashes from time to time.

[khan007]

We are using Crystal Enterprise 8.0 and Domino 5.0.10.
Problem:
We have Crystal Enterprise connected to Domino HTTP using Crystal DSAPI filter. Domino HTTP process hangs/crashes from time to time. Recently, we have seen thread call stack and it is pointing to ebus-3-3-2.dll. This is a crystal DLL. I was wondering if some one know any thing about that or any known issue.

Following is a sample stack trace:
