My system has been running fine for a few years. I have tuned the NSEs previously (https://support.symantec.com/us/en/article.tech251902.html) but went through the steps again.
Ive increased check-in time to 8 hours from 6, and re randomized clients to use the new window. But ever since this past week I have anywhere from 3K to 38K nses in the event queue. They do they process but new ones are coming in faster than it can keep up.
Did a Microsoft patch impact nse processing. We are on 8.5 HF2. i know my setup is correct, so I'm looking for external factors causing issues
