CentOS server. What does it mean when the total used RAM does not equal the sum of RES? All those zeroes bother me. Do me a favor and create a swap file that the OS can use. Follow the instructions here: cyberciti.biz/faq/linux-add-a-swap-file-howto |

CentOS server. What does it mean when the total used RAM does not equal the sum of RES? Does your Java process use multiple threads? Or does it spawn off one or more child processes? That may explain the discrepancy. If a child process is created and destroyed, the OS may not yet have had a chance to reclaim the memory. Can you tell us the nature of the Java app? Does it open a bunch of files? |

CentOS server. What does it mean when the total used RAM does not equal the sum of RES? I think I am mistaken. The total memory as reported by free and top do not include kernel memory. You can find out how much memory the kernel is taken by subtracting the total system memory (check the BIOS) from the total memory claimed by free. In my case, the kernel is taking 2048*1024 - 2057196 = 39956 kB. |
