when i do more investigation i found below issue as well
Pending Callbacks: PPSM->Subdb-DESTROY,PPSM-Sub>Policy-Disc,Policy-Disc>PPSM,
the bundle has two 10G interface that below to the same NP and there is no other subscriber under this NP ,
i wonder if this issue is related to limitation of number of subscriber under Bundle-Ether , or it is related to a different issue
