Hi,
I upgraded GS from 2.0.2 to 2.1-beta2. I now get OOM exceptions and
locking errors (see below) from Java NIO FileChannel (memory mapped
files I think) when serving Shapefiles several times via WMS. Usually
the first rendering after a fresh start of GS went OK. The same
config/Shapefiles did not cause these exceptions in 2.0.2.
I must say that I also upgraded Java/Tomcat and reinstalled native
JAI/ImageIO so here's my current settings:
Ubuntu 9.10 32b, 12 GB RAM, Sun JDK 1.6_22, native JAI+ImageIO, Tomcat
6.0.29, no Gdal bindings.
Tomcat JAVA_OPTS="-server -Xmx1500M -Xms256M
-XX:SoftRefLRUPolicyMSPerMB=36000 -XX:MaxPermSize=512m -XX:+UseParallelGC"
I had lowered -Xmx from 2048M but this didn't make a difference. Ubuntu
has about 6GB of free memory at the time.
Here's the stacktraces (3) and lock error:
