Same here. Always having problems with Kraken. Now tried to withdraw some funds -- errors, as always, stuck at 'Pending'. Cancelled the XRP withdrawal ordered -- stuck at 'Cancel requested'! Funds still missing. Tried another request, still 'Pending'.
An update on my situation: withdrawal 1 now cancelled (after some 12 hours, credited back to account's balance after another hour), withdrawal 2 sent and received; made another request for the cancelled order, still pending. But the withdrawals are working, even though terribly slowly (particularly for a currency advertised as having *immediate* transfers!).
Edit: second withdrawal order cleared after an hour or so, money received on BitTrex, where I'm happily moving with half of my BTC!
