Hi Sedat,

I have a simpler buildroot based rootfs (initramfs based) and LTP is run off of
NFS, although running of a local storage doesn't make a difference.

For me msgctl08 standalone (w/o hassle of running full LTP) is enough to trigger
it consistently.

P.S. sorry my sender address kept flipping - mailer was broken !
