SDLP minister Alex Attwood has accused Peter Robinson and Martin McGuinness of attacking "those who dissent from their draft budget".
Mr McGuinness hit out at Health Minister Michael McGimpsey, who accused executive colleagues to "religiously turning a deaf ear" to the health service crisis.
Mr McGuinness said the executive "will not be lectured by the health minister", describing him as "a semi-detached member of these institutions".
Mr McGimpsey had described Stormont as a "dysfunctional executive" during a studio interview on UTV Live.
Crunch day for Health Minister and Executive next Thursday. No extra cash will probably see UUP walking from Executive. Crisis time.

Mr Attwood said: "The recent aggressive behaviour displayed by Peter Robinson and Martin McGuinness towards those who dissent from their draft budget is very disturbing and is not a healthy or clever way to conduct politics.
"Those who have criticised the budget such as the SDLP, Ulster Unionist ministers and others do so because there is much to be critical of. But the reason Peter Robinson and Martin McGuinness are acting in this way is because they know there is much public anger about this draft budget.
"They have settled on a strategy of attacking critical voices in order to distract from the wildly-held view that they have failed to produce a budget fit for purpose."
But Alliance Party Chief Whip Kieran McCarthy has described the behaviour of the health minister as "unacceptable".
He also challenged his party, the UUP, "to work positively in government or leave".
He said: "The current situation as regards the behaviour of the health minister is totally unacceptable. I am challenging the Ulster Unionists to be positive and help make government here work better or else leave. Government, be it voluntary or mandatory, is about constructive work and partnership. If the UUP can't cope with that they should go."
The health minister has been facing a steady flow of criticisms about the state of the health service in the region since Christmas, including x-ray backlogs and claims that patients' lives are put at risk.
He says he can no longer do the job on the money that is provided.
The Executive will meet next Thursday, followed by a budget vote on 28 February.
A final budget vote is expected on 14 March, ahead of the assembly elections on 5 May.
