Abandontransaction bug (?)

[AlexGR]

I was running 0.15.0.1 in -blocksonly mode and then issued a tx. Obviously it can go nowhere. So I did an abandontransaction and got an error (-5).

Restarted the client in both blocksonly and normal mode later, erased mempool.dat, etc etc, abandontransaction still won't work. I guess I'll have to rescan, but I shouldn't, right?

This is weird, I have successfully abandoned transactions before. Maybe try -zapwallettxs as a final attempt? I think deleting mempool.dat and zapping transactions is what I did.
