Hello, just to report,
Looks like change the message type to simple help to avoid the memory leak.
Just about a day later the memory still OK:
1264 ceph 20 0 12,547g 1,247g 16652 S 3,3 8,2 110:16.93

The memory usage is more than 2x of MDS limit (512Mb), but maybe is the

How many time is neccesary?, because is a production environment and memory

any problem if is done in a low traffic time? (less usage and maybe

Yeah, is also my thread. This thread was created before lower the cache
size from 512Mb to 8Mb. I thought that maybe was my fault and I did a
misconfiguration, so I've ignored the problem until now.
Greetings!

Hi,
I forgot to say that maybe the Diff is lower than real (8Mb), because the
memory usage was still high and i've prepared a new configuration with
lower limit (5Mb). I've not reloaded the daemons for now, but maybe the
configuration was loaded again today and that's the reason why is using
less
Thanks!,
It's true that I've seen a continuous memory growth, but I've not thought
in a memory leak. I don't remember exactly how many hours were neccesary to
fill the memory, but I calculate that were about 14h.
With the new configuration looks like memory grows slowly and when it
reaches 5-6

Hi, thanks for your response.
Clients are about 6, and 4 of them are the most of time on standby. Only
two are active servers that are serving the webpage. Also we've a varnish
on front, so are not getting all the load (below 30% in PHP is not much).
About the MDS cache, now I've the
Hi,
do you happen to have a relatively large number of clients and a relatively
small cache size on the MDS?

Hello,
I've created a Ceph cluster of 3 nodes (3 mons, 3 osd, 3 mgr and 3 mds with
two active). This cluster is for mainly for server a webpage (small files)
and is configured to have three copies of files (a copy on every OSD).
My question is about ceph.fuse clients: I've noticed an insane CPU
