Hi all,
When we start the VMS, internet connection is regularly blocked until we stop the service.
Do you have the same issue ?
Regards,
Robert

Hi Robert,
we heard about this problem from another customer but we have no idea what is going on.
I you encounter this problem next time could you please check the memory usage of the VMS Services?
And please start cmd.exe as Admin and type
netstat -a -p tcp –n
and
netsh int ipv4 show dynamicport tcp
The output of both commands would be interesting.
Which Ventuz version are installed on these machines?
Best Regards
Karol

Hi Robert,
thank you for the logs.
I see two problems here:
1) Your dynamic port range is set from 10000 to 10999 (1000). Which is rather small. A default Windows installation has a port range from 49152-65535 (16348).
2) The VMS service creates multiple connections to 10.0.0.2 and 10.0.0.26. Instead of using one connection they seem to pile up until your ports are exhausted. I want to file this for our developers. Can you give us more information about the network structure? Managed switches, firewalls (software or hardware) between these machines? (Send this information via private message.)
So problem number 2 shows symptoms early because of problem number 1. Without problem number 1 you would have symptoms after 16 times the duration.
I do not know which communication causes these hanging connection but I guess it is the internal messaging between VMS systems. Please try to edit the network config found in "C:\Users\Public\Documents\Ventuz6\Configuration\NetworkConfig.vnetcfg".
And set VMSMessagesDisabled to false.
Your config should now look like this:
Code: Select all
<NetworkConfig>
<Ports>
<Remoting4>19400</Remoting4>
<VMS_V4>19401</VMS_V4>
<Discovery_V4>19402</Discovery_V4>
<VMS2_V5>19404</VMS2_V5>
<VMS_V5>19405</VMS_V5>
<Discovery_V5>19406</Discovery_V5>
<VMS2>20404</VMS2>
<VMS>20405</VMS>
<Discovery>20406</Discovery>
</Ports>
<FilterRules />
<VMSMessagesDisabled>true</VMSMessagesDisabled>
</NetworkConfig>
Then restart the VentuzMS6 (Ventuz Machine Service 2.6) service or reboot your machine.
I hope this helps.
Karol

And do you have any Anti-Virus programs installed?

Hi, now kind of suddenly (after the latest Windows 10 update, 11.1.2020) I seem to have the same issue. As soon as I start Ventuz 6.03.04 , the network stops working completely. The only workaround so far was to turn on Wifi in addition.
Turning Firewall and Antivirus off or on does not make a difference.
