<br />
I understand I can't test *all* of the RAM while it's running but is there a test that can check *some* of the RAM without bringing it down? &nbsp;I have the memtest86 CD already in hand but I don't want to reboot and wait an hour.<br />
<br />
Thanks,<br />

PS. &nbsp;I saw this test below but it's doesn't make sense to me - an MD5 on the same file 3 times will always produce the same fingerprint. <a href="http://www.cyberciti.biz/tips/howto-linux-server-memory-check.html" rel="ugc">http://www.cyberciti.biz/t<wbr />ips/howto-<wbr />linux-serv<wbr />er-memory-<wbr />check.html<wbr /></a><br />
<br />
PS. I'm thinking we've got RAM problems because of the bus error below - it's a bash script that runs every 4 minutes and it hasn't changed in years so I'm thinking maybe it's RAM that's going bad. &nbsp;<br />

Test RAM on Linux server without bringing it down?

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.

Linux OS Dev

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
