And attach the real logs, a thread dump, and let me know if you’re talking to a 3rd party UA server or Ignition’s OPC-UA server. ---

We are using 7.6.2-rc4 64 bit and Ignition’s OPC-UA server. [thread-dump july 02.txt](https://us1.discourse-cdn.com/inductiveautomation/original/2X/5/5577d8f0ba27605d4733d6c9a14967c34d39b141.txt) (64.7 KB) ---

Well I can’t be certain of the cause, but the symptoms lead me to believe that one of the two, or something similar, is happening: 1. The server is totally overloaded for some reason and not sending back responses. 2. Responses are being lost somehow between client and server. (seems unlikely, seeing as it’s a local connection…) What’s the CPU load like? Memory usage? What are the rates of the various subscriptions you have running? ---

The CPU load is low in single digits the memory use is 64%. I have attached a file containing the first six pages of the Subscriptions [Subscriptions.txt](https://us1.discourse-cdn.com/inductiveautomation/original/2X/0/0a3c6939eda932f9aecd4f7fd62a9d28eefec03b.txt) (17.4 KB) [Subscriptions.txt](https://us1.discourse-cdn.com/inductiveautomation/original/2X/0/0a3c6939eda932f9aecd4f7fd62a9d28eefec03b.txt) (17.4 KB) ---

It looks like you have a lot of errors that are saying Ignition cannot find the named OPC server. It’s possible that this is causing your PublishRequestPump error. You could try checking the names of all of your tags’ OPC Server value, I’m sure some of them are pointed to an OPC Server that no longer exists or have a blank path.
