Hm.. well for one thing it seems our os::memory code is buggy on systems
newer than Linux 2.3.23 (i386), and 2.3.48 (all architectures). Ubuntu
11.04 shipped with 2.6.38:
// Returns the total size of main memory in bytes.
inline Try<uint64_t> memory()
{
#ifdef __linux__
struct sysinfo info;
if (sysinfo(&info) != 0) {
return Try<uint64_t>::error(strerror(errno));
}
return info.totalram;
#else
return Try<uint64_t>::error("Cannot determine the size of main memory");
#endif
}
Note that we need to instead return info.totalram * info.mem_unit. I'll
file a bug for this.
It may be related here, since your system is 32 bit, do you have more than
4GB of RAM? It would be interesting to see a dump of the sysinfo struct
that comes out.
I've provided a little program that will print the information, can you
download it and run:
$ g++ sysinfo.cpp && ./a.out
