high memory and CPU usage for version 12.4.1.2

[Chao]

Lansweeper scan service use out all memory, over 10GB.  Any idea how to trouble shoot the issue?

If you open a case, we can analyze your logs and database table and provide some recommendations. The most common culprits are Windows event log scanning and sometimes debug mode.

Already opened a case and sent out the logs.

Same here. I upgrade to version 12.4.1.2 all my Lansweeper server and notice most of them are having high CPU util. I tried restarting services but after quite some time it will go back to High Util. We only experience this after 12.4.1.x version. 

Are there any version update to be release soon?

Check Scanning Queue Size & Frequency

Too many scan tasks queued and running simultaneously can lead to excessive memory use or database load.

1. High-frequency scan schedules (e.g. every 5 mins)
2. Repeating schedules with overlapping scans
3. Very broad IP ranges

Check Performance scanning is enabled if so try disabling to see if that helps. It's possible there are performance scanning targets hogging up the queue since these run in the background and are not visible on the scanning queue

Are you scanning more than just errors with the event scanning. 

SQL Database Performance (if on-prem)
A bloated or underperforming database can trigger memory spikes on the scan server indirectly.

Run database cleanup tool : C:\Program Files (x86)\Lansweeper\Tools

• Stale assets
• History size
• tblNtlog, tblSoftware, tblEventlog

We recently experienced high CPU on our Lansweeper server, we tried stopping/restarting the Lansweeper Service first which fixed it for a while, when it started happening again we stopped/restarted the service again and now it's been at normal usage. 

If the above doesn't work for you, I would open a case with Lansweeper support.
