To improve 128KB block write performance in case of multiple VDEVs ZIL used to spit those writes into two 64KB ones. Unfortunately it was found to cause LWB buffer overflow, trying to write maximum- sizes 128KB TX_CLONE_RANGE record with 1022 block pointers into 68KB buffer, since unlike TX_WRITE ZIL code can't split it. This is a minimally-invasive temporary block cloning fix until the following more invasive prediction code refactoring.
