I decided to just let GCC run while I worked on other projects on my laptop. However, I look up to see that my desktop has restarted. I have 10gbs put into this partition, 8gbs of ram, and a genrous 16gb of swap. Any ideas why it may be crashing?

Could be anything, but you should first try to reduplicate the issue by running the compiler for LFS by itself without doing anything else.

16GB of swap is actually excessive. You really shouldn't use more than 8GB even building large projects like LibreOffice, Firefox, SeaMonkey, or the such.

If the problem reoccurs with the compiler running by itself, you need to start looking at other things.

1. You should monitor your hardware temperatures and see if your CPU might be having heat issues during high load stages. Often high heat can cause a problem and force a shutdown or reboot.

2. Try running checks on the hard disks. Bad blocks can cause problems at times with write backs and could trigger some systems to have a fail safe where it reboots or shuts down a system should a system crash occur.

3. Check your system logs carefully for any fatal errors and such.

Not exactly sure if 16gb swap is good or not. I suspect that it can't hurt to have it. (or I may not understand your config)

Restarting could be from any source agreed. Looking at logs would be first step I'd think.


My guess would be one of two things maybe. Overheating or memory overrun. But could end up being almost any cause.
