GEOM_ELI: Crypto request failed (ENOMEM)

Writing data to a slow USB Stick ( <5MB/sec write, geli encrypted and mounted with noatime) I suddenly
got many of those errors:

>>>  Nov 23 13:07:49 xxxxxxxxxx kernel: GEOM_ELI: Crypto request failed (ENOMEM). label/usbstick.eli[WRIGEOM_ELI: Crypto request failed (ENOMEM). label/usbstick.eli[WRITE(offset=21922807808, length=32768)]

But the written data seems correct.
What's the problem and can it be safely ignored?
