Hi all,
When the hugeshmget01 runs, it gets unexpected signal SIGCHLD/SIGCLD,
and thus stops immediately.
I found two ways to resolve this problem. Please refer to the following
for two kinds of patch.
Well, according to other code structures of hugeshmget0*.c, solution 1
is preferred. But for get_no_of_hugepages
will call popen(), so I think the second solution is the right one.
Will you please choose the right one to apply to
ltp-intermediate-20100119 package?
Looking forward to your confirmation!
Thanks and Best Regards,
shenghui
