Sorry, still no joy - the terminating NUL is missing (I should have noticed this in your v1 already). I suggest to forgo the length check for simplicity because this function is only called with data that is already guaranteed to be less than 1000 bytes, i.e.:

	strncpy(msg, prefix, sz);
/* data is guaranteed to fit due to packet length limit in read_head_info() */
	sz += vsprintf(msg + sz, err, params);
	msg[sz++] = '\n';
	msg[sz++] = '\0';
