Weird stand-by problem (MBWE + MBL)

I have MyBook World and recently got My Book Live. Both are plugged in router, so they are on same LAN.

And I just noticed that after adding My Book Live to my LAN now My Book World Drive goes out of stand-by very frequently. (every 10-15mins?).  (I have manually changed stand-by time to 5mins.)

When I had only My Book World, that almost never happened… I have not changed anything in my book world since i added my book live. So it must be My Book Live causing it.

But im running out of ideas here - where to look, what to suspect…

My Book Live goes in to stand-by mode very well, and in moments when My Book World goes out of stand-by , My Book Live stays in stand-by (LED is blue color)…

I suspected that is this process doing it:

root 21813 0.6 1.2 69824 3200 ? Sl 03:29 0:00 /usr/local/bin/upnp_nas_device -webdir /etc -desc nasdevice.xml

But no… i stopped it, but going out of standby continues.

Checked /var/log/messages on my book world - found nothing unusual.

Checked disk activity using

                         echo 1 > /proc/sys/vm/block_dump
                         dmesg -c
                         echo 0 > /proc/sys/vm/block_dump

, also found nothing. It just shows bunch of following messages about changing LED status:

oxnas_wd810_leds_state state=1
oxnas_wd810_leds_state state=3
oxnas_wd810_leds_state state=1
oxnas_wd810_leds_state state=3
oxnas_wd810_leds_state state=1

Access from internet on my book world is allowed only to few non-standarts ports, no i’m sure that is not causing it.

So, question is, is there possibly something on My Book Live, that is causing weird LAN activity and such way breaking other box from stand by? I have powerful router, I can block ports/services, but i have no idea what it might be…

Any idea might be useful.

Did you ever find out why this was happening?

No, not yet :frowning:
