- The Server appears to be running but is unresponsive.
- The Server is unreachable with either Nx Desktop or through a browser.
- Sometimes only a part of features might look not responding, others work fine.
- Server restart cures the issue for some time.
Occasionally processes executing within a Server become, for better lack of a word, hung up.
These types of issues are considered very critical by Nx Team as they give the appearance of normal, functioning Server and as a result do not notify the System admin that recording has been disabled. As a result it is imperative that any person seeing this issue follow the steps below so that the Nx Support and Dev teams can identify and rectify the underlying causes.
Follow the steps below and open a support ticket:
- If possible - please dedicate the scenario that leads to the server process freeze.
- Archive Media Server logs folder
C:\Windows\System32\config\systemprofile\AppData\Local\Network Optix\Network Optix Media Server\logIn Linux:
- Make a memory dump of the running process and archive it.
1) Open the Task Manager (Ctrl+Alt+Del > "Task Manager")
2) Click More Details or Show information for all processes
3) Find the process Nx Witness Media Server
4) Right-click it and select Create dump file
5) A message will display showing the location of the new dump file.
1) Follow the method described here: https://serverfault.com/questions/173999/dump-a-linux-processs-memory-to-file
2) After that run commands in terminal:
- $echo "t apply all bt 25" | gdb mediaserver-bin PATH_TO_DUMP >report.gdb-bt 2>&1
3) report.gdb-bt will be the result file Nx Team needs for the investigation.
- Wait for 5 to 10 minutes, try to make more actions with the software that display the symptoms. Try to rename the server in the resource tree. Sometimes having two memory dumps simplify the search of the thread that caused the hang.
- After that create one more memory dump and archive it as well.
- Restart Media Server as a temporary solution.
- Assign separate support ticket at our portal attaching all collected information. Pay attention to the dump file size. Zendesk allows to attach up to 20 MBs size files. So most likely you'll have to share the file with some cloud storage service. More details you describe -- higher chance that issue will be fixed sooner.
