The best way to capture what is happening will be to get a simultaneous DAVE Trace and tcpdump of the mount, then the disconnect. Here are the steps:
- Login to the Mac with a local admin account
- Launch DAVE Tracing (in the /Library/Application Support/DAVE/ folder)
- Check all checkboxes except Server and Printing
- Enter local admin credentials when prompted.
- Quit the Tracing utility
- Restart the Mac

- Launch the Terminal application from the /Applications/Utilities folder
- Enter the following into the Terminal window, hitting return after each line:

Code: Select all

cd Desktop
sudo syslog -c 0 -d
sudo syslog -c syslogd -d          #(this may return an error that can be ignored)

sudo sysctl -w com_thursby.cifs_global_options=0x405fff
sudo tcpdump -s 0 -w disconnect.pcap host XXX.XXX.XXX.XXX 
   (where XXX.XXX.XXX.XXX is the IP address of this Mac)
- Enter your password when prompted
- Leave the terminal window open

- Using Go->Connect to Server, mount the share. Please make a note of the name and the approximate time that you mount the volume.
- Work as normal until the disconnect occurs. If possible, please note the approximate time of the disconnect.

- In the Terminal, hit CTRL-C to stop the dump

- A file should appear on your desktop named disconnect.pcap. You will need to compress this file for easier email transmission (right-click or CTRL-click, then "Compress...").

- Launch the DAVE Tracing utility
- Choose "Save..." from the "File" menu
- Please use the problem description are to provide the information requested above
- Send the two files (DAVE_Tracing.tar.gz and to

Once the Support Department has received the files, we'll go over them to determine why the problem is occurring.
