You need to provide some more information to get some help from this forum. For example:
1. What to you mean by a communication crash (e.g. symptoms, error codes or messages, etc.)?
2. Does it occur immediately or after a while?
3. How do you fix it?
4. Is this a new communication link?
5. If it is an existing communication link that worked before, what has changed?
6. What have you done to troubleshoot the problem?
