I update Cpanel to latest version, compile apache to use all php modules to latest except Java, install compile run everything except JSP and interchange. I left over 20MB free of RAM in sysem status. Min RAM for VPS is 256MB. If I install JSP and interchange, do I need to additional 128MB or 256MB of Min RAM in order to run? If I keep install to run everything, will there be data loss and OS corrupted? I tried to install everything but something went wrong after that.
