The system will freeze when running a high load memory application, or an application using a large portion of memory. I tested with a MySQL process using just over 6GB and the system will have an uptime of about 4-5 days before it freezes. I have also tried running Nutch (with JDK1.5p2) and it will run until the resident memory size hits 101M (the “size” memory is at 2.2GB captured through the top application at the same time). Running in either “Hardware” or “Disabled” mode for Memhole mapping will not cause the machine to freeze, but will remove about 1GB of RAM from the OS. Kernel memory output with Software selected: Oct 16 03:29:28 link kernel: real memory = 9663676416 (9216 MB) Oct 16 03:29:28 link kernel: avail memory = 8288559104 (7904 MB) Kernel memory output with Hardware or Disabled selected: Oct 16 04:04:47 link kernel: real memory = 8589934592 (8192 MB) Oct 16 04:04:47 link kernel: avail memory = 7246278656 (6910 MB) >How-To-Repeat: Run MySQL with a large memory size, greater then 4GB or use any application that requires large portions of memory with high read/write activity. >Fix: I don’t know of any fix, but if your willing to run with 1GB less of RAM you can use either Hardware or Disabled mode selected. >Release-Note: >Audit-Trail: >Unformatted:
