[LTP] msgctl11 TBROK Not enough free pids

[LTP] msgctl11 TBROK Not enough free pids

[Romu Hu]

Hi,

msgctl11 in ltp-20110915 failed on 2.6.39 kernel:

msgctl11    1  TBROK  :  Not enough free pids

I found that before error out,

MSGMNI is 32768
MAXNKIDS is 10
free_pids is 32611
maxnkids = ((free_pids / 4) / MSGMNI);
so maxnkids is zero, which is why msgctl11 failed.

Is this problem of testcase or problem of the tested system?

Thanks

I changed MSGMNI in /proc to below 3000 and test passed.

Thanks
