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.

Subject: Re: [awips2-users] Automatic Clearing of AWIPS II's memory for
prolonged use.
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.

We’ve been exploring the [mis]use of AWIPS II as a substitute for NAWIPS in our
department hall display for radar/satellite and obs.
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.
Cheers and Thanks
