Today I got this when building kernel:

# fg
make -j6 buildkernel
*** Stopped -- signal 18
Child (49737) not in table?
couldn't resume aicasm_macro_gram.o: No such process
*** Signal 1
1 error
*** Error code 2
1 error
*** Error code 2
1 error


I have kern.randompid=777, and I did stopped buildworld just before
building kernel. Maybe this is (tcsh) shell issue?
