I don't know what the problem is, but I can tell you that strace "attaches" to
a process meaning that it begins to watch the process to see what system
calls it is making. If the process doesn't make any system calls, then you
won't see anything with strace. For example,
#define BIG_NUMBER 4e15
main () {
long x;
for(int i=0; i<BIG_NUMBER; i++)
x+=i;
}
When this small program is in the loop, it will not be making any system calls
(i.e., no output/input or other system calls) so it will be a very busy
process but it won't show anything in strace. Hope that answers your
question!
