Hi Cyril,

With value of msgmni 8000 it worked well for me but i want to understand which part from the log (produced by strace or some other method) i should be focused on to get to know ohkk it is failure because of value of msgmni is more.
How you analyzed and helped me to fix ,what approach you have followed ?

Thanks

Try with less, I suppose 8000 should work fine.

If estimating how many processes we can run was easy the test would have
been fixed a long time ago.
