Relay: freezes frequently

The problem is that the relay seems to freeze. At that point all remote sessions are halted. The only way to get out of this is to restart the service itself. Nothing is logged in the error and connection logs of the relay server.
Task manager on this VM shows that resource usage (RAM, disk, network) is very low. So it doesn't seem like a hardware issue.
As it is, this does not look stable for extensive use, which would be a blocker for me... Any ideas on what to look for?

Thank you for your message.
Could you please clarify if there is any antivirus/firewall software installed on the RU Server machine? In case if there is, then the issue might be caused by the software blocking the rutserver.exe. We highly recommend that you add the RU Server folder C:\Program Files (x86)\Remote Utilities - Server\ to the antivirus exceptions list.
Also please check that the outbound ports required for the RU Server are not blocked/used by some other software. For more information on what ports are required to be open for the RU Server please refer to this page.
In addition, could you please clarify what version of Remote Utilities do you use? If you use the 6.10.10.0 version or older versions, then please try updating the RU Server to the latest version - 2.9 Beta 1 and see if this helps to resolve the issue. The 2.9 Beta 1 version is available for the download on this page.
When updating RU Server please make sure to update both Viewer and remote Hosts to the corresponding 6.12 Beta 1 version as well - the version mismatch might lead to performance issues or some features not working. You might try updating just one of the remote Hosts and one Viewer or even use the portable Viewer first to see if the issue still occurs when using the updated version of Remote Utilities.
Please let us know if the issue persists.

This is a Windows 7 SP1 VM. No antivirus was running from the start. I used to have the Microsoft firewall enabled, but I've disabled it as well.Polina Krasnoborceva wrote:

Also please check that the outbound ports required for the RU Server are not blocked/used by some other software. For more information on what ports are required to be open for the RU Server please refer to this page .From what I understood reading that page, basically inbound port 5655/tcp should be open. This is what we have done from the start. However outgoing access to port 5655 (for viewer or host access) [b]was blocked. The reason was that the viewers and hosts are not accessible from the relay: only the viewer/host can connect to the relay, the other way is not allowed.
We are using the latest releases 6.10.10.0 for viewer and host and the latest stable relay version.In addition, could you please clarify what version of Remote Utilities do you use?

We could try to update the relay only, and also some clients. But upgrading all the clients is difficult currently. Would there be a problem if we did not change the viewer and host, but only upgraded the relay to 2.9 beta 1?When updating RU Server please make sure to update both Viewer and remote Hosts to the corresponding 6.12 Beta 1 version as well - the version mismatch might lead to performance issues or some features not working.

Thank you for the clarification.
Yes, you are absolutely right, on the RU Server's side, you need the inbound TCP 5655 port to be opened, not the outbound.From what I understood reading that page, basically inbound port 5655/tcp should be open. This is what we have done from the start. However outgoing access to port 5655 (for viewer or host access) was blocked. The reason was that the viewers and hosts are not accessible from the relay: only the viewer/host can connect to the relay, the other way is not allowed.
Of course, we actually suggest not to update all of the remote Hosts and Viewers at once, it's best to update just one remote Host and one Viewer (or even use the Portable Viewer and Agent). However, please note that if you update the RU Server, then it's best to update Viewer and Host as well since the version mismatch might also cause other performance issues and some features not working.We could try to update the relay only, and also some clients.

Please let us know if the issue persists after updating Remote Utilities to the Beta version.
