In PVA Power Panel you may see the situations when resource alert (red triangle) remains next to the container's name though resource usage has already returned to normal.
The alert icon is kept there for some time, depending on the node's configuration for alerts expiration. Each resource can have its own expiration timeout, and the default value of 1 hour might be too much for memory related resources.
The internal request to review the default configuration is registered as PVA-34197.
The default expiration timeout of 1 hour for resources with rapidly changed consumption can be decreased: in PVA MN, open the hardware node's page, click "Configure..." in the top of the right panel and select "Logging" in the pull-down menu. Memory and CPU parameters can be reconfigured to be updated in some shorter intervals (few minutes).
If there are any clients confused by this resource alert, please suggest them to check "Resource Alerts" tab in order to check resource alerts history - it's quite easy to tell if there are active resource issues by looking into the log.
