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 think it's a configuration issue.

Cyril, do you think is it better to change TBROK to TCONF here?

(quoted diff) +1 -1
-                       tst_resm(TBROK, "Not enough free pids");
+                       tst_resm(TCONF, "Not enough free pids");

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

Thanks
