These errors are caused by the kernel memory (specifically,
"ata_composite_zone" UMA zone) depletion. To get this knowlege, one should
Read The F[ine] Sources, as ata(4)/ataraid(4) lack the DIAGNOSTICS section:
ata-all.h:#define ata_alloc_composite() uma_zalloc(ata_composite_zone,
M_NOWAIT | M_ZERO)
