Saturday I upgraded to NPM 11.5.1 and implemented SAM 6.2 hotfix 1 into my environment, which consists of 2 polling engines. Now every few days, SolarWinds begins flooding our environment with application down alerts. When I've checked, all the alerts are coming from devices on our additional poller, and what I've been able to isolate it to is the Service Host:Remote Procedure Call is using so much memory is seem the jobs are queuing up and not truly being sent out. The only way to resolve this is a server reboot. Now, this wasn't a problem until after the above upgrades were done. Since this is isolated to SAM component alerts and not alerts on the nodes themselves, I'm tempted to think the issue lies in the SAM hotfix. I've opened a support case, but have not heard back from anyone yet. I wanted to know if anyone else had been experiencing this. We are running on Windows Server 2012 R2.
