I installed Tomcat 7 via Easyapache 3. I am not sure about Tomcat 7 package including Java, so I tried to install Java JDK/JRE individually. Then I enter java -version to command line, but I encounter a error: Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. I have Centos 6.7, 64 bit, 1gb ram server. What should I do? Thank you Kind regards

  Hi, I think you don't have enough RAM available in your server. How much RAM available in your server ? Check the RAM status using command: free -m
