Is this for testing purposes?
I think there is a flaw in your design. As Dustin said, your machine is not
going to be happy about 5000 concurrent IO operations unless you have 5000
cores.
Java's concurrent package is very easy to use and has low overhead-- take a
look at ExecutorService. Maybe
Hi, theese threads simulate users. I have jboss AS that manages all user
requests and for every request i need to update memcache. I will try spy
client tomorow.

Indeed, I was somehow wondering "why a Q for no reply?" ;-)
Anyway, it makes sense. I guess my issue is fully client side then.

That's a great start. I'd love a slave if you can contribute one:

Yes. I'll setup a machine you can login an try to rebuild yourself with the

This includes the toolchain for the release i try to build.

your problem might indeed be related to the danga client.. if you take
a look at its connection pool (SockIOPool i believe) it has a lot of
synchronized code, which isn't very happy in a highly concurrent
environment. i recommend at least doing a test with the spy client to
see if it actually help
I assume you are running memcached in any kind of unix.
So do you had the java virtual machine and the memcached runing in the
box while you got those errors?. If so, forget about the network. But
you could check how busy is your box when you start those threads
(mem, cpu)
On the other hand, see
Every thing is one one machine in development, but it will be separate
server for the memcache with LAN.
Yes i tried it. What should i see? It stop updating the cache while i get
the exceptions above.

That's a problem, because a lot of issues have to do with clients.
Anyway, how healthy is your network?.
Have you tried running memcached with -vv (two 'v' and not a 'w' and)
and see the log in the server?

Hi, it is not up to me to change the client.
First thing I would suggest: use a modern client. The Danga client is
getting old, but the Spy client is up-to-date.

OK,
i wrote simple test to show you what is happening. I create 100 threads, and
i start them at the same time. They begin to update the cache.
public class UpdateableObject implements Serializable {
public int i = 0;
}
static int i = 0;

Hi,
Before 4 months i had to create cache for data stream messages coming from
TCP stream about 400 per second every second. I had to keep the last message
only. I implemented MDB that received the messages and updated the memcache
but it couldn't take the pressure. May be i didn't configured it c
We have a few thousands updates per second per box with memcached
(linux with eight core each) and the box hardly reports any activity.
The only problem we had was the terrible slow .net serialization and
the md5 computed when we plug hibernate with memcached.
In my experience, the bottlenecks at
Hi,
trying to investigate an issue on the replicated delete of
libmemcached, I found out that the no reply delete command is replying
something in case of error (as "key not found"), which makes it pretty
hard for the client library to follow the messages count and not work
as expected in certain

Well this is not actually true. I tried to update memcache before with about
10 messages per second every second and it began to throw some IO
exceptions. I am using theese classes:
