I don't think it needs one because it's not on the list if controlled exports
like some crypto is?

Hi,
I changed the limitation (it is now variable) but parse the key is actually
quite long (about 1 hour for a slab to 30M!) Do you have any idea what I
could improve?
thank you

Is it possible to create multiple slabs for items of the same size? To have
slabs of reasonable table.

I have just pull a request to the github that contain some improve I made it
some days ago. The stats cachedump command dump all the keys (including
expired), so if just dumping the non-expired keys, it will perform better.
We have not yet used this feature in product environment, so use it

I am afraid you can’t.
But you can modify the option –f to make the slabs more “closely size”;
And you also can use more cache instances with a client support consistent
hash. It make fewe
Thanks! It might take me a while to look into it more closely.
That conn_mwrite is probably bad, however a single connection shouldn't be
able to do it. Before the OOM is given up, memcached walks up the chain
from the bottom of the LRU by 5ish. So all of them have to be locked, or
possibly some t
Sorry for the late response.
My CPU utilization normally is min 2.5% to 6.5% max.
So it's interesting you ask this. The reason why I submitted the 1st
question is because I've experienced some random CPU utilization spikes.

Please upgrade. If you have problems with the latest version we can look
into it more.
You can also look at command counters for odd commands being given: make
sure nobody's running flushes, or "stats sizes", or "stats cachedump"
since those can cause CPU spikes and hangs.
With 1.4.20 you can use
I run every minute stats, stats items and stats slabs.
the only commands executed are remove, incr, add, get, set and cas.
I'm running now with 6 threads per instance with 3 per server and haven't
had the issue again, not that this change fixed it.
I'll definitely update.

Those three stats commands aren't problematic. The others I listed are.
Sadly there aren't stats counters for them, I think... Are you sure it's
not completely crashing after the CPU spike? it actually recovers on its
own?

I think this issue has something to do with our access pattern (although we
run very limited commands and not very high traffic either).
We always start having issues on the same instance (I guess because of the
system accessing a specific key). When we notice the issue we bounce the
instance with
oh, and the memcached processses never actually crash and die. we end up
manually bouncing them.

No command can take up much time. If all other commands hang up, it's
either a long-running stats command like I listed before, or a hang bug
(though I don't know why it would recover on its own). We've fixed a lot
of those since .13, so I'd still advocate upgrading at least some
instances to see i
Dear all,
Thank you very much for your reply.
I don't use crypto like OpenSSL and so on.
I understand that there is no need to ECCN.
Is that Correct?
