Hi Stefan,

I have seen a mon grow quite high on Bobtail.  Joao had some theories

know it is on his stack.  Background here:

Hi all,

As Travis points out, this has been seen before.  I've spent a fair 
amount of time chasing this down now, but haven't got to any useful 
conclusions yet.  Although this is concerning, chasing down this kind of 
behaviour tends to be a time sink and there are other more pressing 
issues that have been requiring most of my attention.  This hasn't been 
forgotten and I've been allocating my time to it as possible.

On Sébastien's issue, that may very well be caused by some of the 
memleaks that have been fixed some time since argonaut, prior to bobtail.

I'm expecting to be able to find the time Real Soon Now to put a doc 
together with ways, for anyone willing, to provide us further insight on 
what's happening.  The monitor is supposed to be able to dump a heap 
profile (using gperftools) on-the-fly, but I recall having some issues 
with that not so long ago, so that's probably one thing to look into asap.

In any case, Stefan, do you by chance still have that monitor going?  If 
so, are you able to tell us what's that monitor rank? 'ceph mon_status' 
should help you assessing that.  Furthermore, assuming you are using a 
version prior to v0.58, any chance you can run a 'du -chs 
/var/lib/ceph/mon/ceph-foo', with foo being the mem-hogging monitor's 
id, and then, if you notice an abnormal disk consumption on one of the 
directories, dive in to check where said consumption is happening?

Thanks - that would be great i'm willing ;-)

Sadly not i needed the memory ;-)

No idea what you expect to see but all mon servers consume 180MB of disk
space.

[: ~]# du -chs /ceph/mon
180M    /ceph/mon
180M    total

Cool, good to know.  I'll post something to the ml as soon as I have 
something worth sharing.  Most likely next week.  It's unlikely I'll get 
around to do it still this week.

eh, just trying to figure out if said memory consumption is due to some 
large map being kept in memory.  Given we always write to the store when 
maps are updated, and only after that do we load them to memory, I was 
hoping to see some incredibly high disk consumption (while the monitor 
was running) in order to assert whether the mem consumption would be 
tied to some specific map.  But given that the store is periodically 
trimmed this was a long shot anyway. Still worth a try though ;)
