Insight - "The network connection is down"

We are seeing intermittent problem across several clients on our network, (and not necessarily all at the same time). Yesterday afternoon it was all clients!, but normally it is only 1 or 2.

 

When trying to save or check files in we get an error, "The network connection is down. Contact your administrator for assistance".

 

The obvious thing would be to check if the network is/was down. This does not seem to be the case. We have also been scouring the network logs and cannot see any issues.

 

Has anyone else experienced this?

 

My suspicion is that Solid Edge/Insight is VERY sensitive to the netwok connection. If there is any glitch it throws it's hands into the air and gives up. (Just a theory!)

 

Re-starting Solid Edge does not help. The files seem to save in the local cache, and eventually it does seem possible to synchronize and check the data in.

 

Thanks

The usual suspects are:

- Virus scanner

- Port scanner

- Firewall

- put the Insight Website to the trusted sites

 

Hope this will help!

 

Kind regards

Re: Insight - "The network connection is down"

I have seen this message when either the database server or the web server is running low on disk space.

Have also seen it when a user was removed and re-added to the domain under the same name.

Running out of diskspace is a very good hint.

 

Very often the Transactionlog of the SQL will occupies a lot of diskspace and this log is sometimes bigger than the origin database. Even the checkout from a document from the website is than impossible.

Re: Insight - "The network connection is down"

We have had this same issue. Haven't found a fix for it but we found that it seemed to be when trying to save a single document with a large file size into Insight. I couldn't give you an exact number but somewhere over 20Mb would give us problems.

Re: Insight - "The network connection is down"

That problem is probably related to the IIS limit on upload.

Search on IIS maxAllowedContentLength.

GTAC Solution Center article 002-7002749 covers how to set the maxAllowedContentLength limit:

 

Cut and pasted below for your reference:

 

  • If the Sharepoint server is running on a Windows 2008 or Windows 2008 R2
    operating system there is a default maximum file size of approximately 28 Mb
    set by Internet Information Services 7.0 and 7.5. (IIS).  You can overcome this
    limitation by editing the Web.config file that is located in the
    "C:\inetpub\wwwroot" folder.  At the end of the file you should see the
    following lines of code:
    
    <system.net>
    <defaultProxy>
    <proxy autoDetect="true" />
    </defaultProxy>
    </system.net>
    </configuration>
    
    You will need to insert the following lines between the last "</system.net>"
    and the "</configuration>" line:
    
    <system.webServer>
    <security>
    <requestFiltering>
    <requestLimits maxAllowedContentLength="52428800"/>
    </requestFiltering>
    </security>
    </system.webServer>
    
    After the edit the code should resemble the following:
    
    <system.net>
    <defaultProxy>
    <proxy autoDetect="true" />
    </defaultProxy>
    </system.net>
    <system.webServer>
    <security>
    <requestFiltering>
    <requestLimits maxAllowedContentLength="52428800"/>
    </requestFiltering>
    </security>
    </system.webServer>
    </configuration>

 

Re: Insight - "The network connection is down"

Thanks for all the responses!

 

This is where I am up to.

 

The Usual suspects are all good. Also nothing here has changed, and we had pretty much every client wiht the problem on Tuesday. Wednesday Morning, everyything was clear!

 

Disk space is good. Easy 600gb free.

I don't know of a user being removed and re-added. I'll follow this up, however given the size of our organization and who has access it would be unlikely.

 

My money is on the 28mb limit! We are running Windows 2008 R2.

A bit of a ask around revealed one of the users has a 29mb part!

*** Would this casue all of the users to have the issue? We had 7 clients go down!

 

I'll make the changes outlined in the Gtac article 002-7002749 and see how that goes. (Thanks uk_dave and Jason). Although the error we get is that the network is down. This article, (and others) seem to refer to a "cannot find document....." error.

 

Stay tuned.

Re: Insight - "The network connection is down"

The PR: 6801732 describes you problem. But maybe your DB is write protected for some reason. Check the permissions of the Insight user that has the access to the DB.

 

We had the case that the IT-Admin has done some changes in the user management and we lost the permission to get write access to the DB!

Re: Insight - "The network connection is down"

The web.config file we have is different to that specified in the GTAC article. However it looks as though the file limit has been changed to ~200mb already.

 

Another look a the available space on the server revealed it is indeed Full!!!!.

 

We only have about 20gb of data filling a 250gb space!!!!!

 

We have looked at and implemented the various suggestion for shrinking the transaction logs according to the Microsoft Technet. But it doesn't look like this is enough!

 

Can anyone advise what the transaction logs are for, and why we need them?

Is this not simply a case of deleting old logs, or will that be disastrous?
