Sets are asynchronous, so what's happening is you're overwhelming the JVM with
object futures, and then they're timing out before they can actually get to the
server.
For instance if you changed line 28 from:
client.set("key_" + i, 600, value.getBytes());
to:
client.set("key_" + i, 600, value.getBytes()).get();
It'd be slower, but all of the items would get there since you'd be waiting for
each one to complete before sending another. I think this is what you thought
your code was doing.
There are a few variations on this too, like filling a blocking queue and
grabbing items from the other side to send to the server, rather than creating
requests super fast, that the network IO has to take time to deal with.
In fact, your test looks a bit like the built in LoaderTest:

- Changed state: Invalid
from spymemcached.
I don't really understand, why this bug marked as "Invalid".
Currently the objects net.spy.memcached.protocol.ascii.StoreOperationImpl,
net.spy.memcached.protocol.ascii.StoreOperationImpl, and others keep growing in
the heap without any limit. As a result - the heap is exhausted, and we have
big Full GC stop-the-world pauses.
The right behavior shall be the following: these objects shall be put to the
queue with configurable size and configurable RejectedExecutionHandler
(CallerRunsPolicy or AbortPolicy).

I don't understand why the client should be responsible for either throtteling
requests or querying in a stop-and-wait fashion (which performs poorly,
obviously). That's the library's job, IMHO.

it is invalid because you're using the default queue with the default
constructor. you can specify a queue for the client to use, allowing you to
control resources as you request
