Hi
Our Geoserver was, again, out of service. Version 2.3.1 on Ubuntu 12.04
server. I found several Java heap space errors, similar as below. Heap size
is alrady 512.
512M is not that much, generally speaking.
I would settle for something between 1G and 2G.
2014-12-05 12:05:44,042 ERROR [geoserver.ows] -
java.lang.OutOfMemoryError: Java heap space
We would need a larger portion of the logs + more info about how you
use geoserver.
A memory dump might help. Check this page on how to get a memory dump
from a live geoserver:
http://docs.geoserver.org/latest/en/user/production/troubleshooting.html#using-jdk-tools-to-get-stack-and-memory-dumps
Then this flushedPos error
2014-12-05 12:38:26,552 ERROR [geoserver.ows] -
java.lang.IndexOutOfBoundsException: pos < flushedPos!
This is not a problem, it is a client that kills the connection while
geoserver is writing on the output stream.
In the more recent version this warning can be ignored setting QUIET
logging level.
And after restart this kind of warn and error. We have installed 2.3 over
2.2 so may be somethin to do with that?
2014-12-08 13:46:30,655 WARN [geoserver.security] -
/data/data_dir/security/config.xml.2.2.x could be removed manually
2014-12-08 13:46:31,288 ERROR [geoserver.security] - Error loading filter:
guiException
This looks like an harmless warning, unless you are experiencing
failuers related to security, like not being able to log in and so on.
In spite of my several notices, our sys admin still has java 7 (64-bit) on
the server. Is that the reason for heap size errors
JVM Version Oracle Corporation: 1.7.0_01 (Java HotSpot(TM) 64-Bit Server
VM)
I don't think so. You should be fine with Java 7.
Geoserver is still using Jetty.
So, what to do to prevent those errors?
