I observe the same lapse on NetBSD if the volume is created and started.
On a side note while looking into this issue - I uncovered a memory
leak too which after successful registration with glusterd, Self-heal
daemon and NFS server are killed by FreeBSD memory manager. Have you
observed any memory leaks?
I have the valgrind output and it clearly indicates of large
Emmanuel,
Could you take statedump* of the glustershd process when it has leaked
enough memory to be able to observe and share the output? This might
give us what kind of objects are we allocating abnormally high.
* statedump of a glusterfs process
#kill -USR1 pid of process

KP,
I do have a 3.2Gigs worth of valgrind output which indicates this
issue, trying to reproduce this on Linux.
My hunch says that 'compiling' with --disable-epoll might actually
trigger this issue on Linux too. Will update here
once i have done that testing.

Harsha,
In addition to the valgrind output, statedump output of glustershd process when
the leak is observed would be really helpful.
thanks,
Krish

Nope spoke too early, using poll() has no effect on the memory usage
on Linux, so actually back to FreeBSD.

This is a small memory system like 1024M and a disk space for the
volume is 9gig, i do not think it has anything to do with AFR per se -
same bug is also reproducible on the bricks, nfs server too. Also it
might be that we aren't able to capture glusterdumps on non Linux
platforms properly - one
Harsha,
I haven't gotten around looking at the valgrind output. I am not sure if I will
be able to do it soon since I am travelling next week.
Are you seeing an equal no. of disconnect messages in glusterd logs? What is
the ip:port you observe in the RPC_CLNT_CONNECT messages? Could you attach
Sure will do that! - if i get any clues i might send out a patch :-)

Right. Once you will have this one, I have Linux-specific truncate and
md5csum replacements to contribute. I do not
So here is what i found long email please bare with me
Looks like the management daemon and these other daemons
eg: brick, nfs-server, gluster self-heal daemon
They work in non-blocking manner, as in notifying back to Gluster
management daemon when they are available and when they are not. This
