After saving AI file - immediately save as PDF and get this error. "The save file operation failed"

After saving AI file - immediately save as PDF and get this error: "The save file operation failed".
Eventually it saves. But what concerns me is sometimes I discover that my AI file never saved, but the PDF did. I thought maybe i was saving my PDF before the AI file finished saving, but sometimes I get the error after closing and opening the AI file after saving it.
Any suggestions?
