Plugin Apache Log4j JAR Detection (Windows) (156001) on version 202201200227.

Has anyone got any customer feedback if the updates have improved and reduced resources?

For two weeks, I've seen numerous scans where PowerShell has launched from the scan and 100% memory usage.

Both times the feedback from Tenable support has been the plugin has been modified (sensors up-to-date with the latest plugins in both instances) however this leaves me to test on production environments.

    Hi,

    In our environment the resource usage stopped after I updated all the plugins on all the scanners.

    Tested the scan on agent and remote scanned machines and powershell "only" consumed around 700MB RAM and caused no issues. The scan time is much longer, it was 5 minutes on my pc now it's 50 minutes.

    Previously my agent scanned client pc and remote scanned windows server crashed because of too much memory consumption.
