Subject RE: ISO Download Failing

It looks like it was a memory issue on the NFS server. I started a remote
session and the server was taking a long time to respond to commands, and
all the RAM was being allocated to the cache. After a reboot I tried another
import, this time it transferred the file quickly. I checked it's resource
usage and RAM is back to normal. We'll keep an eye on it and see how it
performs.

Thank you Ilya for your help!

Tim,

I may have experienced a similar issue a while back. See if you can run
tcpdump on SSVM to check for any issues and as to why this happens. I don't
believe SSVM uses wget when it puills the ISO, sniffing and analyzing the
pcap file would be better.

This is shot in the dark, check the memory utilization and SSVM, maybe you
are running out of RAM? I've seen this in past as well, but I was running
non-stable development version of CS.

Do you see anything in the logs for CS Management Server and SSVM under
/var/log/cloud/?

Regards
ilya
