Re: inconsistent map behavior

 

开云体育

Looks like an obvious failure due to not enough memory allocated to the Java runtime on the second machine.?

How much RAM memory does that computer have, and what operating system are you using? Also, what version of the Java runtime are you using? Open a terminal or command window on the system, and at the prompt, type the command

java -version

(Note the space between the "java" command and the "-version" option.)

Assuming the computer has enough memory available, you may need to raise the Java heap limit with a command-line option to the "java" command used to launch YAAC. If the computer doesn't have enough RAM, it may need an upgrade. :-(

Hi Andrew,
thanks for the reply. Both machines are running 1.0beta208.

On the first (working) system, the error log shows repeated downloads of the NWS map file, e.g.:
Wed Feb 19 10:59:42 EST 2025: downloading CONUS_L2_CREF_QCD_20250219_155839.tif.gz took 675d+6223r+9680e msec

On the other (non-working) machine: I only see the first download and then the listed error:
Wed Feb 19 11:16:32 EST 2025: downloading CONUS_L2_CREF_QCD_20250219_161441.tif.gz took 613d+7230r+8184e msec

This sounds like there's some kind of networking issue on your second computer. This can happen when the radar image refresh is attempted and fails. An error message should appear in the YAAC.out file in your log files directory (also viewable in the Help->About dialog on the Error Log tab, and in the terminal window where you started YAAC if you used one). Whenever you successfully download a radar image, the log should report the refresh time (when NWS says the image will be out-of-date), so you should be able to predict when YAAC will try to download the image again.

What build of YAAC are you using?

Subject: [yaac-users] inconsistent map behavior

I have the current YAAC version running on different machines. On one ( a RPi 4) NWS raster overlay maps are displayed and refreshed every few minutes. On the other, (an x86 machine), the maps do not refresh. If I delete a previously loaded NWS map, and manually load a new one, the map displays. Subsequent maps are not displayed. If I look at the "raster maps" window, I always find the enable box unchecked. This happens even though "enable" is checked after loading the first map. Have I mis-configured the second machine somehow?
