For me problem gone after disabling 

options         CAPABILITY_MODE         # Capsicum capability mode
options         CAPABILITIES            # Capsicum capabilities

in kernel conf 

I'm found it when roll backing system to previos revisions. 

On r254268 uniq inside i386 jail say that  = "unable to limit rights for "

So I decide to check without Capsicum features...
