Im trying to get Solr up and running, at first I had the JDK.1.6 working fine, then tomcat running fine too. All of a sudden when trying to run Solr for the first time however I get the error message:
[root@78 bin]# ./java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Ive deleted Tomcat, deleted the JDK and reinstalled the latest JRE but still get the error message even when trying to get the version number of Java.
