Problem was not in limits, but in geli. I have RAID5  array (it is 
absolutly correct, checked several times whith dd(full read and write). 
I created encrypted partition on this array and put jail dirs on it. 
When i tried to start jail, i received that:

limits fails when tried to read file ld-elf.so.1 (found experimetally 
:). when i try to read this file manually, no error occurs.
