In the generaltion of Moshiach - talmidei chachomim there will be claims made against talmidei chachomim - Greenblatt-Kaminetsky Heter

It is interesting to note that criticizing talmidei chachoim is one of the signs of the time of Moshiach. On the one hand that could be understood as there will be unjustified attacks on rabbonim in the time of Moshiach. However it clearly also can be understood to mean that Moshiach will come when the masses  criticize gedolim who corrupt the halachic process and go against the Torah and as a result undermine emunas chachomim by their actions

Kesubos (112b) R. Zera said: R. Jeremiah b. Abba stated, ‘In the generation in which the son of David7 will come there will be prosecution8 against scholars’. When I repeated this statement in the presence of Samuel, he exclaimed, [There will be] test after test,9 for it is said in Scripture, And if there be yet a tenth in it, it shall again be eaten up.10
