Hi folks I just wanted to throw this topic out there. I don't see a lot of information out there and this issue has a huge impact on performance and some people may be wondering where things can be improved within the system.
We were experiencing what appears to be a memory leak with SWIS v3 on our main web poller so I opened a ticket to see where it would get.
Here is what I learned:
- Solarwinds support says this is a known issue and that it is fixed in v12.0.1
- SWISv3 will build up memory @ a rate of about 100 MB a day until it is killed/restarted
- Orion Improvement program (OIP) is installed on every host, even if you choose not to participate. This is a big deal because this is sending information out of your network to google analytics.
- Uninstalling OIP seems to correct this memory leak
We've observed our web server for a week or so now and the memory seems to be stabilized in the 400-600 MB range on the SWIS v3 service
Also, I installed NPMv12.0.1 on my QA environment and the OIP was installed again even though I chose not to participate.
