1) "with status.." what status? Did your give us a full error text?
2) Maybe, you are out of memory - then, operation system kills the process (this is specifically true under Linux)
3) It could be internal calculation error. Does single-thread FLUENT solves the problem correctly?
You could autosave your calculation every N (e.g., 300) iterations, then, after fail restart from the last saved file.
4) if your parallel FLUENT fails every time independently of the task being solved (with different problems/case-files), it could be defective memory card
