You can also verify whether this issue is present by running netstat -aob > ports then searching for :666 which will show QDS is listening on this port on the QDS machine.
Cause
This is caused by a defect introduced in builds SR10 (11.20.12742) and higher where port 666 was left open in those builds. This port is used for trace debugging by R&D internally and whenever the port is scanned, Distribution Services will crash.
Resolution
Options to resolve (in order of speed and ease):
- If server is on an internal only network: Turn off internal port scanning for port 666 on that server
- Turn on Service Recovery options: Under Administrator tools > Services > QlikViewDistributionService > Recovery > First/Second/Third failure: Restart Service
- Upgrade to 11.20 SR13 or higher/Request a patch with the standard patch diligence procedure
