SAS EG Frequent Disconnection From Work Tables

Hi All,

 

I currently face an issue where several SAS EG users with my client are facing disconnection from their respective work tables. They are unable to run their reports because of this reoccurring disconnection from their work-space servers, but in the back end I can see that their programs are running in the respective servers. 

 

We are having a Grid Environment with 3 Compute servers and 1 Metadata server. On discussion with the respective users, I can see them many of them are having several instances of SAS EG open from the same machine and are connected to multiple compute servers.

1) Is this a frequent issue with SAS EG? How can we solve this disconnection issue?
2) Could this be because of users having several sessions open and being connected to Multiple servers for their work tables?

Please let me know if you have any solution for this issue.

Sounds like something that you should probably work with Tech Support on and most likely verify your network connection stability.

I have already verified with the Network team, they have confirmed that this is not an issue from their end after verification.

As already mentioned by @Reeza, I recommend you open a track with SAS Technical Support. This type of problem often requires checking SAS server logs and possibly EG logs to diagnose potential causes, of which there are many.

Hi @blindgaurdien16

 

Technical Support is the way to go, I agree with previous comments.

 

In the meantime, you may want to review those SAS-Notes (if they match your version of SAS Enterprise Guide):

  Problem Note 47825: Network firewalls might prematurely terminate long-running tasks or queries submitted from SAS® Enterprise Guide®

  Problem Note 49637: SAS® Enterprise Guide® might randomly lose its workspace server connection

  Problem Note 42679: SAS® Enterprise Guide® might disconnect from a workspace server when you are running programs that generate a large log

 

Hope that helps.


Cheers,
Damo

Hello @blindgaurdien16,

 

I completely agree with the approach to contact SAS Technical Support.

 

I would recommend you:

- to check the SAS notes provided by @Damo

- your network people check the timeout of connections, often the culprit. If you are in Grid and perhaps even with Ciitrix, either Citrix or an F5 might have timeouts for the connections and firewall settings to be checked.

- the logs of your Object Spawner 

- if nothing of above works, share your problem with your SAS Technical Support office
