Error in Starting of Tomcat server

[Kalpesh Gaikwad，修改在11 年前。]

I am getting following error when i start the tomcat server.

"Error occurred during initialization of VM
Could not reserve enough space for object heap"

Please Help me...

You're running out of memory. Liferay requires at least 1G of free memory space. So your machine must have at least 1.5 GB

There is 6GB Empty space in my system drive i.e. C Drive & my systems RAM is 1 GB.
Yet i am facing this problem.

Hi Kalpesh,

I believe Ricardo is referring to the fact that you must properly allocate at least 1GB of memory to your Tomcat using JVM args on startup. See this article:

You won't be able to run Liferay with the default settings in a machine with only 1GB of RAM. You can make it work if you run Linux with only console (no X) and decrease heap size and PermGen size way down but you won't be able to run anything else on that machine and even then you are going to run into OutOfMemoryError quite often. With minimum recommended settings you are going to need at least 2GB of RAM just for running the OS and Tomcat. If you want to run anything else you are going to need even more RAM.

If you have only 6GB of hard disk space and 1GB RAM then you are in a desperate need of a modern computer.

I have a test site setup on a virtual machine with CentOS with only 1 GB RAM and about 600MB HDD. However, I'm running CUI and have database and file system on a different vm. I have to delete/stop all unnecessary services. It's useful to testing out clustering techniques but definitely not for development nor production.

Doing a build-service on liferay portal-impl requires much more memory too. :-)

I got solution by changing
Liferay Setting ->Memory args -> -Xmx1024m -XX:MaxPermSize=256m to Liferay Setting ->Memory args -> -Xmx1024m -XX:MaxPermSize=128m.

Thanx to all...

You actually decreased the maximum memory size and it worked?

Hitoshi Ozawa:

Yes, It works. :-)

I am also facing the same problem. My System is running on 2GB RAM. When I was starting catalina.bat it was not able to start properly..

In Eclipse Juno, I added this server as tomcat 7.0 server, it started then in the eclipse. But it's unable to open the homepage, ie http://localhost:8080/ and it was saying 404 page not found..


Please give me a reply..

I am new to Liferay Portal apps.

I am sending the screenshots of those problems..

Hi Rama,

Can you please check and tell what is your liferay memory configuration. Basically, if your system memory is 2 GB you can't allocate complete 2GB memory to JVM.

Cheers

This actually worked for me, after several hours of frustrating alternatives. Nice one!
