Debug logs from Zmanda Windows Client (ZWC) help the Zmanda Support team to troubleshoot issues involving Windows client hosts. They contain:
- Debug logging from the ZWC Service
- Configuration settings
- Information about your operating system environment
ZWC Support utility collects the above information and packages them into a log archive. By default, this archive is created in
C:\ProgramData\Zmanda\Zmanda Client for Windows - Server Edition(x64)\misc

- When the ZWC Service crashes, there should be a memory dump file in
C:\ProgramData\Zmanda\Zmanda Client for Windows - Server Edition(x64)\misc\CrashDump. Verify that the file was recently created.
- Collect and send logs as described above in the first section of this article. The dump will be collected along with the rest of the ZWC logs when you use the
If a memory dump is not found in the CrashDump folder mentioned above or if this folder contains a file but it is not a recently created file, a memory dump may still be able to be acquired using the Windows Server Action Center as described below:
- Control Panel => System and Security => Action Center
- Expand the “Maintainance” section and click the “View reliability history” link
- Click the “View all problem reports” link at the bottom of the window

- Please also collect the ZWC logs as described in the first section of this article as these will be needed along with the memory dump to diagnose the cause of the crash.
