Memory keeps growing to cause the pod to restart

[jaredhshuai]

I define many custom property for logEntries:

public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory)
{
//... something
foreach (var allProperty in AllProperties)
{
var data = dataContext.GetData(allProperty);
if (data != null)
{
var prop = propertyFactory.CreateProperty(allProperty, data);
logEvent.AddOrUpdateProperty(prop);
}
}
}

When I execute LogInfo repeatedly, the memory keeps growing. I ran the service in the k8s cluster and finally exceeded the 1G memory limit, causing the pod to restart.

I don't have any configuration for PeriodicBatching, so it uses the default value, that is, BoundedConcurrentQueue has no upper limit. The reason why memory continues to grow is that the consumption is too slow and the production is too fast?
If so, what are the best practices for configuration?
