Fresh instalation. OpenKM v 5.0.2 (from OpenKM-5.0.2_JBoss-4.2.3.GA.zip) on windows server 2008. JDK 6 update 24 for x64 (jdk-6u24-windows-x64.exe)

Get often this OutOfMemory error when I do simple thing. Java.exe process often get out of control and used 100% of cpu non stop.

Here is one exemple of error:

Code: Select all

Describe me your hardware specifications, memory and number of cpu's

You can try with it on run.bat and can increase Xms and Xmx depending your server memory and programs installed ( the best scenario is using openkm in a isolated server )

Code: Select all

JAVA_OPTS="-Xms256m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=128m -Djava.awt.headless=true"

Intel(R) Xeon(R) CPU X3470 @ 2.93GHz with 2GB of RAM, 1cpu

It run on VM from VMWare

I already increased memory in run.bat to

Code: Select all

set JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx1024m

I before try with

s

Code: Select all

et JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx768m

Same result.

Thanks

obviously you've not put -XX:PermSize=64m -XX:MaxPermSize=128m that's for heap
