Reject Code IND-196-01

My return was rejected with Code IND-196-01.  The initial explanation was not understandable, but when I went back into the return, it said, "Due to a timing issue or a processing error that has been corrected.  No changes are needed to your tax return, it just needs to be e-filed again."  So I re-e-filed it, and it was immediately rejected a second time.  Two questions:  1)  How many times can I re-e-file my return (I do NOT want to mail it!), and 2) Would you recommend that I wait (a day, two days . . . ?) before e-filing it a third time.  My message said the problem had been corrected, but that doesn't appear to be the case.  Thank you for your advice!
