Hello,

We have been tracking an issue for more than a few months now and have no explanation as to why this is occurring. Was curious if anyone has seen this type of error before and if you were able to correct it. We have also had an IFS Engineer spend roughly 8 hours troubleshooting with no luck.

We are using IFS 9.10 and Oracle 12.

This Out Of Memory Error does not show up consistently in a given area or if performing a certain task. This pops up all over the place. We have 100 users in our environment and only maybe 5 report this non-stop. This error forces you to restart IFS but once restarted it could go days before seeing the issue again. We started by replacing the end user machines for the troubled 5 users that see this consistently, with no resolve.

Thank you,

Hi @zconverse,

I found similar issue has been solved by @Imal Thiunuwan of an internal post. Since you won’t be able to view it, I will re-post here. Not sure if this solves your issue. 

IEE > Tools > Options >  Advanced tab

 

Then,

  • Reduce the Number of Pages
  • Under Display section, untick both options

 

/Nimesh

@Nimesh Kasun Thank you for the response.

We did experiment with those settings under the Advanced Tab but it did not have an impact.

For good measure I will review these settings on the user machines to verify.

@zconverse Did any of these settings improve the stability of the client sessions?

We see this error also.

 

 

Hi @zconverse and @jhainsworth,

 

This error is related to Operating system’s graphic rendering (Windows) and indicate that it has encountered an error in memory. This error message is a generic error.

 

Following Microsoft blog discuss about this error in-depth,

https://docs.microsoft.com/en-us/troubleshoot/developer/dotnet/framework/general/wpf-render-thread-failures

 

Take a look at section with title ‘Causes of the failures mentioned above’ in this link for causes for this error. And follow the recommendations given under the title ‘General recommendations’.

 

Hope this helps.

Hi @zconverse and @jhainsworth,

 

I highly suspect that the GDI (graphics device interface) object value might be the reason for this issue.

 

First check the GDI object value for IFS Application for users who got this error. Please follow the below path. 

 

Windows Task Manager > More details> Details tab> Right click on one of the column names > Select columns > Tick GDI Objects > OK

 

By following above, the GDI column should be visible in the task manager. Please check the GDI object value related to the IFS Application when user is using the IFS application for specific tasks.

 

Please note that the default GDI object value is 10,000.

 

Best Regards,
Tharindu
