Hi Gang;

For the past few years the SC conference has had a NDT server on the show 
floor.  This year I used the Knoppix live cd which supports both the NDT 
server (http://ndt.sc06.org:7123) and the NPAD server 
(http://npad.sc06.org:8200).  The server came up about 3 weeks ago during 
the hot-stage process and it's major user is the local infrastructure group 
setting up the conference network.  Yesterday morning they came in and 
reported that the server was failing with a Protocol Error! During the S2C 
throughput test.

I jumped on the server and started looking around and found that the USB 
thumb drive file system was full.  This caused the NDT server to fail with 
the Protocol Error! message.  It started working again after freeing up 
some space on the drive.

So it looks like there is a bug in the code around some of the logging 
functions.  If the log message fails, then the next test gets a protocol 
error message.  I'll look into this shortly (once SC ends) but at least I 
know what to start looking for.

I'll let everyone know when this gets fixed.  In the mean time, if you are 
running a server from the Knoppix Live CD, check your backing store or 
maybe try writing the log file to /dev/null.
