Hi,

We can not longer open our project due to this error: OutOfMemoryError: Java heap space

Does anyone know how to fix this?

Try setting and/or increasing the Max Heap before launching the Designer:

Hi Kevin,

The same error is still occuring.

This is on the gateway.

Critical Issues

High Memory

The Gateway is using more than 90% of available memory.

Allocate more memory to the Gateway process or alter your project to reduce the workload.

Probably ought to give support a call and let them take a look.

Gateway heap space is allocated in the ignition.conf file (under <Ignition install directory>/data/ignition.conf)
