java.lang.OutOfMemoryError: Java heap space

We tried to make OpenKM as intuitive as possible, but an advice is always welcome.
Forum rules: Please, before asking something see the documentation wiki or use the search feature of the forum. And remember we don't have a crystal ball or mental readers, so if you post about an issue tell us which OpenKM are you using and also the browser and operating system version.

java.lang.OutOfMemoryError: Java heap space

I need help in my OpenKM- Environment.
I have the following Environment:
- Server Windows 2008R2 64-Bit, 2 vCPU, 4096k Memory
- Server version: Apache Tomcat/7.0.27
Server built: Mar 31 2012 03:43:36
Server number: 7.0.27.0
OS Name: Windows Server 2008 R2
OS Version: 6.1
Architecture: x86
JVM Version: 1.6.0_34-b04
- set JAVA_OPTS=-Xms1024m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m -Djava.awt.headless=true -Dfile.encoding=utf-8

the start of the Java machine works.
after the start is the CPU load to 50-70% During this time, no user can log in
after about 2 hours, an error message will appear: java.lang.OutOfMemoryError: Java heap space.

Does anyone have an idea or solution?

x86 architecture is a limitation for java taking advantage of all memory in your computer.
what openkm version are you trying tyo get running, because jdk 1.7 is right version to be used on latest openkm versions

Has anyone found a solution to this problem? I am receiving "java.lang.OutOfMemoryError: Java heap space" constantly.

I am using OpenKM v 6.3.0 (build: 8156) on a Lenovo laptop (Intel Core i7-4600UCPU@2.10GHz, 8GB RAM) running Windows 7 Enterprise sp1, 64-bit.

Following instructions in the article "Howto Increase 'Java heap space'" I modified C:\openkm-6.3.0-community\tomcat\bin\Catalina.bat with

set "CATALINA_OPTS=-Xms256m -Xmx512m -XX:MaxPermSize=256m"
(tried to increase the max size to 1024, but OpenKM crashed immediately when started)

Here is the most recent log information:

Seems HSQL has not enought memory to start at the begining, change the paramter -XX:MaxPermSize=512m to -XX:MaxPermSize=1024m

Consider migrate to 64 bits architecture and also to MySQL. I think both things are good idea to be done.

Re: java.lang.OutOfMemoryError: Java heap space

Thanks for the reply.

I tried increasing the MaxPermSize from the original 256 to 1024, but OpenKM crashed immediately (as it did when I set the max heap size to 1024). I tried 512 and OpenKM started up fine, but still comes back with Java heap space errors as before.

I am already using Windows 7 64-bit.

Not sure how to migrate to MySQL but will consider it. Do think there is a relationship between the database and the Java heap error?

Hoping for a conclusive solution to this issue. I would like to propose OpenKM to my colleagues, but cannot with the current errors.

Thanks again!

Much of the documentation refers to the architecture of the installed JVM. I seem to be running 64-bit, shown by:

C:\windows\system32>java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

C:\windows\system32>java -d64 -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Installed programs indicate both Java 7 & 8 and both 32 and 64 bit versions (see attached image).

OpenKM still fails to start if I increase the maximum memory allocation (ie. -Xmx or -XXMaxPermSize) beyond 512m.

Can anyone address this issue?
