is there a memory limit for the memcached process ? i want to run it
with -m 4096 option , is that possible ?

What happens when you try?

actually ..i wanted to procure more ram. but someone just said that it doesn't allow more than 2 gig. thats why i wanted to confirm. right now i am on a 2 gig machine. but want to run memcached with 4 gigs of ram

Well if the machine had 4gb of ram, I wouldn't use 4096 for the -m option. As I am sure that the OS and other bits are probably using some memory there. I'd do 3800 or something, but depends on what else is being used on that server.--

it has 8 gigs of ram and its 64 bit
its going to be dedicated to memcached

Compile memcached as a 64bit binary and you should be able to use as

By the way, has anyone already tried to quantify in a *more
scientific* manner the actual extra memory we should let on a box to
be sure memcached won't swap ?
I guess memcached related overhead should be proportional to the
expected number of connection and their traffic. I guess this is about
the same for the OS with its internal buffers. But I must confess that
so far, I don't know the exact multiplying factor(s) ...

It's at least "a couple megs". It depends on how many parallel connections
you have, and the typical size of your read buffers.
If you do a lot of large multi-gets, you'll use more ram than otherwise.

can anybody tell me how we can decrease the RAM size of MemCached
