Hi Ethan,
I've tried to use my test server again today, and have found that it's
getting a Java heap space problem. I then restarted my server and it
can load the large dataset. However, if I refreshed the page, I get the
Java heap space problem.
Ahh, I tried that restart/reload a few more times, and it seems like it works for the first few loads, and then any large dataset will result in the error.
Having said that, if I went back through the smaller dataset, TDS will
show smaller dataset fine.
This is what I get in catalina.out:
2007-05-09T12:17:27.275 +1000 [ 3495267][ 97] ERROR - thredds.servlet.CatalogServicesServlet - doGet req= http://ngdev.sf.utas.edu.au:8080/thredds/catalogServices?catalog=http://ngdev.sf.utas.edu.au:8080/thredds/catalog/argo_csiro/catalog.xml got Exception java.lang.OutOfMemoryError: Java heap space 2007-05-09T12:17:27.294 +1000 [ 3495286][ 97] ERROR - thredds.servlet.ServletUtil - handleException java.lang.OutOfMemoryError: Java heap space java.lang.OutOfMemoryError: Java heap space
I tried to setup the remote management thing in tomcat without success, so I'm afraid I can't give you more details until I can get that up and running.
Cheers,
-Pauline.

Did the cache permissions solve the problem you were having with scanning directories that contain large numbers of files? Was the scanning to generate a catalog or was it an aggregation?

HI Ethan,
Yes, I've noticed that occasionally it will show an OurOfMemory error.
I'm currently running is
THREDDS Data Server Version 3.14.02 Build Date = 2007-03-19 23:50:44 JVM is java version "1.5.0_09" Tomcat is: 5.5
Wow, the oddest thing just happened. I noticed that catalina.out were printing out messages saying that tomcat had problems trying to access cache.log. So I went in and change the ownership of all cache* and then THREDDS was able to load those big datasets without problems. Oops, sorry! I should read the log more carefully!
Thanks,
-Pauline.
