java.lang.OutOfMemoryError: Java heap space #3
Description
While using the C++ client to fetch a keyrange, I get this exception:

Basically, I'm doing this:
void dump(std::shared_ptr<kinetic::BlockingKineticConnection> bc){
std:: string last_key(4096, '\xff');
int count = 0;
for (kinetic::KeyRangeIterator it =
bc -> IterateKeyRange("", true, last_key, true, 1000);
it != kinetic::KeyRangeEnd();
++it) {
printf("%s\n", it->c_str());
count ++;
}
std:: cout << std::endl << "count=" << count << std::endl;
}
