This is expected behavior.

Let me quote Oracle documentation:
"Export issues the following return codes:
0 is a normal (successful) completion. Review results carefully as a 0 return code can indicate an error not serious enough to terminate the utility, but invalidates the Export file.
8 is an end due to an irrecoverable error.
