Does it hang during normal operations, or does it hang during boot?<br />
<br />
If it boots and runs for a while before it quits, then it is likely a bad memory stick.

You can do an init 6 fine? Or it hangs too? <br />
<br />
I'm not sure about the hardware issue. It's pretty uncommon that a system doesn't crash when encountered a memory/cpu problem. Or at least, this is my experience.

I have a E450 running Solaris 7 which hangs with solid Acitvity LED light. &nbsp;No keyboard lights, no other lights, no crash dump, nothing in auditing. &nbsp;I can get the machine backup up and responsive by either cycling power or pulling the keyboard plug and replugging it in. &nbsp;No response to L1A.<br />
<br />
What else should I check?<br />
<br />
No, not under maintenance; can't upgrade Solaris versions, etc.<br />

Thanks!

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
