Hi,
I am using dirvish to backup my harddisk. The backup storage is on
another harddisk all with in the same machine. I have 20G of RAM
installed on this machine. I noticed that after dirvish run the memory
footprint of the system increases from around 700Meg to almost 6Gig. If
I disable dirvish, there won't be any memory usage increase. The
interesting thing is you can not find any process that uses this amount
of memory but free command showing this amount of memory is used (not
cached). The only way to get rid of this extra memory usage is to
restart the machine. Here is the output of free and smem command after a
dirvish run:
==========================
# free -lm
total used free shared buffers cached
Mem: 20116 14105 6011 0 1693 6240
Low: 20116 14105 6011
High: 0 0 0
-/+ buffers/cache: 6170 13945
Swap: 37347 0 37347

As you can see there is a big difference between the memory usage
reported by these two tools. Here is the spec of the machine and dirvish
config files:
==========================
# cat /etc/issue
Debian GNU/Linux 6.0 \n \l
==========================
# uname -a
Linux arash-pc 3.2.0-0.bpo.3-amd64 #1 SMP Thu Aug 23 07:41:30 UTC 2012

# cat /etc/hostname

# cat /etc/hosts

# cat /etc/dirvish/master.conf

I really appriciate any help and thanks for your time.
