============ I am also having a problem on my 64meg of ram dns-323 when trying rsync from drive to drive. I can rsync from a remove machine onto the dns-323, but I recently rsynced 1600GB on lenny and had no problems pre-upgrade to 6.0. Any help would be greatly appreciated as I love this platform. ---------- Forwarded message ---------- From: Martin Michlmayr <[email protected]> Date: Mon, Feb 14, 2011 at 9:24 AM Subject: Re: dns-323 upgrade form lenny to squeeze final To: brossmeisl <[email protected]> Hi Brian, * brossmeisl <[email protected]> [2011-02-13 20:37]: > First off, thank you so much for making it possible to install > debian on the dns-323.

It might be worth asking on the debian-arm to see if other people see the same problem. I would have assumed that 64 MB RAM should be enough but then again I don't know what you're running on your DNS-323. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
