I'm not sure why that is, I've stopped and started it at least 4 times today and several yesterday. ---

Did you get the right logs from the right gateway? Are you sure you're restarting the gateway you think you are? Not sure there's any other explanation. Gateway restarts are very clear in the logs. ---

Definitely the right gateway logs. I'm starting and stopping with the bat files. I'm currently doing a screen share with Loren's. He restarted the service and it still didn't fix it. We're now the process of doing a fresh install. ---

Also just ran into this bug while developing an Edge project and resetting the trial many times. Gateway restart fixed it. How is it possible to have a memory leak, I thought Java had a garbage collector? ---

> [@Zachary\_Zipper](#): > > How is it possible to have a memory leak, I thought Java had a garbage collector? Garbage collectors collect unreferenced/unused memory. A memory leak is caused by accumulating references to memory without releasing them. ---

Seems to still be a living bug in 8.1.43? Just experienced this same issue. ---

As noted for the OP, this error is almost always a **symptom** of a memory leak elsewhere in Ignition. Ignition's OPC server is just a heavy consumer/recycler of memory, so it is often the canary that signals "something's wrong". You should start a new topic, and provide lots of details on what might be leaking memory. ---

**Adding a tip for users without admin access** : If you're unable to restart the Gateway using administrative methods, such as restarting the service via services.msc, gwcmd, or similar tools, a simple backup and restore operation (that could be done through web) can also trigger a Gateway/Edge restart.
