Well now I am confused. I have that option set to No (even though the default is Yes) because of
this post way back. The setting dialog is a bit confusing as to what is going to happen. If I set it to Yes, it regularly flushes the cache so that the memory watchers don't get nervous but, if I set it to No, it use the memory as it sees fit and flushes as memory is needed. The No setting would seem like the router is managing the memory as it sees fit. A yes setting would be a regular schedule of clearing it. Do I have this backwards or am I mixing up two separate things?
