NI OPC Server Fault - Bad_OutOfMemory

Hello everyone, I am trying to connect NI LabView (V5.11.262.0) OPC UA Server 2013 (32-Bit OS) in Ignition 8.1.13 (64 bit).
I have already set all the certificates to trusted (both in Ignition and NI LabView Configuration) and established a Client server communication successfully, But I still get an error while connecting to the OPC Server which says "status=Bad_OutOfMemory, description=Not enough memory to complete the operation."
I tried to recreate the certificate and remaking the OPC UA Server connection which failed. Does anybody know about this or have faced similar issue ? I will attach the screen of the error message popup.

UaServiceFaultException: status=Bad_OutOfMemory, message=Not enough memory to complete the operation.

Give Ignition more memory? (In ignition.conf.)

Sorry, I forgot to mention that ignition gateway is running on a good enough memory buffer I have allocated 6GB of which almost 2-3GB are free at any given point in time. Also would like to point out that the LabView computer is running on a 32bit OS (Windows 7) which has 4GB ram out of which only 50mb is available and Ignition is running on a different PC on a 64 Bit OS (Windows 11) which has 32gb ram.

This is the NI server reporting OutOfMemory, not Ignition. Try restarting it or contacting their support.

@Kevin.Herron is right here, NI support is probably your best bet. I have had LabVIEW give me this error a few times before and it has almost always been related with an error in how I was trying to configure LabVIEW to interact with the host machine or another computer (e.g. having LabVIEW run a .bat file on the host machine). Luckily, NI's technical support staff is not the worst (not as good as Inductive's though :slight_smile: ).

Thank you @Kevin.Herron for your quick response will contact NI Support and ask them for solution. @swolnisty thanks for sharing ur experience. :slight_smile: :+1:
