A full recount and recheck has been ordered in Ireland South after a request by Sinn Féin candidate Liadh Ní Riada following the 18th count.
The count will resume again at 9am, where the last three seats, including the so-called Brexit seat, remain to be filled.
Earlier, Fianna Fáil's Billy Kelleher took the second seat following the elimination of his party colleague Malcolm Byrne.
Mr Kelleher exceeded the quota on the 17th count.
He joined Seán Kelly of Fine Gael in securing a seat in the constituency. Mr Kelly topped the poll and secured the first seat.
Independents4Change candidate Mick Wallace is virtually guaranteed a seat. He is on just over 109,000 votes after the 17th count.
Ms Ní Riada is in a tight battle with the Green Party's Grace O'Sullivan, and Fine Gael's Deirdre Clune, with one of the three set to miss out.
