Hi,
We've experiencing severe failure on our production enviroment of Dspace.
The system crashes and goes down constantly (every 2 or 3 hours
approximately).
The logs show this message:
14-Jan-2015 09:11:50.035 SEVERE [http-nio-80-exec-8]
org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun
java.lang.OutOfMemoryError: PermGen space
The characteristics of our server are the following:
Processor: Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz
RAM: 8 GB
SO: CentOS Linux release 7.0.1406
Dspace version: 3.3
Apache Tomcat: 8.0.15
Java: 1.7.0_71
After several hours finding a solution, some changes to the JAVA_OPTS
environment variable were made. This is how it is set right now:
JAVA_OPTS="-Xmx4096M -Xms4096M -Xmn128m -Dfile.encoding=UTF-8
-XX:NewSize=128m -XX:MaxNewSize=128m -XX:PermSize=256m
-XX:MaxPermSize=2048m -XX:-UseGCOverheadLimit -XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled -XX:NewRatio=16
-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/logs-dspace/tomcat
-Dcom.sun.management.jmxremote"
Is anyone have experienced this problem? And how can we resolve it?
Thanks in advance for any help.
Bender
