Hi Everybody,
I would like to ask and to be confirmed that anybody has or has encountered
with the following issue:
When I try to generate cache from geotif based raster imagemosiac (the data
compression inside geotif is jpeg) and the number of tasks to use is more than
one, after 1-2 minutes generating the Geoserver together with Tomcat will
crash. (Only linux kill command and then a Geoserver (re)start could help.)
If the number of tasks to use is one all going well.
So I suspect that it could be a data race or some other issue with
multithreading.
I have tried to further investigate the problem and after long searching I
found the followings:
To gain more speed for jpeg reading, the libjpeg-turbo (version: 1.5.0) has
been installed.
Because of the compression type in geotif is jpeg, the server finally will find
and use libjpeg-turbo for decompression.
After that when I removed libjpeg-turbo from the LD_LIBRARY_PATH, so the server
cannot find it, the problem has been disappeared.
So my question is that could it be a Geoserver bug, or I have to report that in
another forum(s) (maybe the problem could be in the java binding or in libjpeg
turbo).
I know that the jpeg compression is not the best for raster but we got the data
in this format.
If you try to reproduce the problem, here are some technical details:
I use Geoserver 2.9.0 with java jdk1.8.0_121 on Oracle Linux Server release 6.9.
The web container that is running Geoserver is Tomcat 8.5.11 (with
tomcat-native).
The native JAI and JAI ImageIO also have been installed.
Best regards,
Tamás
