HI Mike: I was able to get a few more hours of time with CAVE-D2D by increasing the memory but the creep of accumulated data no longer used since it’s deep in the past still slowly builds. We set the regional settings to State (for UNR) which I assume only captures a subset of the memory-heavy data but we still have to start things over with a fresh CAVE-D2D run.

Hi Bill, Are you seeing this memory warning with D2D or NCP or both? Dev comments note that "perspectives can override the default behavior to take more extreme actions to reduce memory usage", but it's not clear if or how this is done by D2D or NCP (I'm looking into it). A solution is to increase the maximum memory available to CAVE by changing "-Xmx" in /awips2/cave/cave.ini from -Xmx2560M to -Xmx6144M This 6GB max will be the new default in future CAVE releases (beginning with 16.2.2), which will hopefully prevent this warning message.

The display is more than satisfactory for several hours especially with the use of both radar and satellite (as well as watches and warning) on the same display screen. But at the end of this grace period we are hitting a memory “rope limit” that results in a dialog box shown before. “This CAVE is nearing its maximum memory limit. Performance may degrade significantly 50MB available. Consider closing tabs, clearing panes or reducing the frame count to free up memory” (this happens with even modest frame counts). Can AWIPS automatically clear its cache of by-past images that are outside of the current data display window? I presume that this is how NAWIPS did this.
