[OpenAFS] Win 1.3.84 hangs 2003 Server + stats
Thu, 14 Jul 2005 07:08:41 -0700
AFS Server running on a 733MHZ Linux 2.4/afs 1.2.11 = system "S"
AFS Client running on a 2.6Ghz Win 2003 Server = system "C"
The test is to backup all of the data from server S to a local drive on
client C using copy and paste on C.
The cpu load on C was about 90% during the copy prior to the crash (OS froze
Windows also reported that some files were being overwritten on C which
should be impossible. I.e. the afs client appears to be handing duplicate
files to the windows file system.
I just ran a smaller 100G test and after the files were copied the afs
client C remained at 55% cpu load doing nothing. It should be 0%. There was
no network traffic at 0% cpu load.
To duplicate the test just drag and drop a large directory structure to a
local windows drive.

This is one of the worst support requests I have ever read.
I have no idea what you are attempting to do.
Are you attempting to install the AFS Server on a Windows system?
Are you attempting to install just the client?
If your CPU is at 90%, what processes are using all of the CPU?
If you are attempting to install the AFS Server on a Windows box, how is it
that the server is 1.2.11 and the client is 1.3.84?
