Hm... I think the problem is more serious than that. My builds are failing on any sleep statement (that is, /bin/sleep, the executable).

Indeed, '/bin/sleep 1' causes it to go off into lala-land, and truss is of no help.

The following test executable waits forever:

#include <unistd.h>
int main() { sleep(1); return 0; }

I am running on VMware, though.


I think the problems you are seeing might be fixed in the
latest kernel as there was a small fall over still from the
timer changes. This was affecting the operational priority
values of programs because of time slice priories were
a little mixed up. Can you try and update to the latest kernel
build and see if that fixes the problem your seeing...
