The warning came amid bickerings between the alliance partners over the release of hardline separatist Masarat Alam last Saturday.
State Deputy Chief Minister and BJP leader Nirmal Singh met party president Amit Shah in Delhi and apprised him of the situation in the state in the wake of the controversy over Alam's release.
After the meeting, highly-placed BJP sources said a terse warning has been given to PDP top brass that "any such unilateral action will not be tolerated any more".
Meanwhile, the state government appears to have softened its position, saying it will not free any more political prisoners or militants.

"There is no such thing", the State Home Secretary Suresh Kumar said on being asked whether government will continue with the release of more militants and political prisoners.
"No Public Safety Act could be re-framed against Masarat Alam, that is why he was released. Rest there is nothing more (releases)", Kumar told PTI in Jammu.
"As per the Supreme Court Judgement you cannot detain anyone again and again on the same charge. If you have done that there should be fresh charges against him", he said.
Pushed on the backfoot over Alam's release, Union Home Minister Rajnath Singh today asserted that his government's top priority is national security and not the continuance of government in the state.
His remarks came on a day Opposition parties in Parliament upped the ante against the Government over reports that the Jammu and Kashmir government was planning to release 800 more separatists and sought to know if the state's Governor has mentioned this in his report to the Centre.
