here's an update on my memory issues:<div><br></div><div>I switched to a thin client with local apps setup. Now 512M is plenty of memory for chrome as a local app if everything else runs from the ltsp server. I was using fat clients because of network slowness. Looks like fixing flow control is going to help my network actually use the gigabit port in the server. <span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 16px; color: rgb(90, 51, 32); "><u><a href="https://help.ubuntu.com/community/UbuntuLTSP/FlowControl">https://help.ubuntu.com/community/UbuntuLTSP/FlowControl</a></u></span></div>

</div><div><br></div><div>I do expect that with only 512MB of ram I will need remove anything extra - thanks for the suggestions. This appears to be more like a memory leak, however, I'm wondering if it's related to the lucid x memory leaks found during beta testing. I can't seem to find what's hogging the swap memory?</div>

</div>In my initial tests with diskless fat clients, I also ran into some<br>
memory problems on a 512MB machine. Disabling certain things that run on<br>
startup (most notable jockey-gtk and italc) reduced the memory usage<br>
quite a bit and made it possible to log in and use the machine much better.<br>
<br>
It doesn't quite sound like you have the same issue that I had, but<br>
perhaps even removing some of these session startup programs might fix<br>
yours as well.<br>
