Re: Copying more than 500 MB crashes Fedora Live CD even though there is sufficient RAM
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 hi I noticed this as well when trying to download an image of sonar linux from a fedora live environment. The download would get part way through, usually around 20-21 percent, then fail. I thought it was my network connection, but afterwards nothing else worked. Applications wouldn't launch, bits of gnome would fail to work, etc. This explains it. I was actually worried this was a general linux issue, but if it's a fedora one it's probably a simple fix Thanks Kendell Sent from Sonar GNU/Linux Moez Roy wrote: On Thu, Apr 16, 2015 at 4:13 PM, Moez Roy moez@gmail.com wrote: Copying more than 500 MB crashes Fedora Live CD even though there is sufficient RAM.

I don't think this is a question meant for the devel list. You would be better off asking on the users list. Also when you do ask it there, please make sure you give a lot of data you did not in this email. 1) Which of the many 'Fedora Live CD' are you referring to. 2) What is the hardware you are trying to install it on. (x86_32, x86_64, ppc, arm) (type of computer if possible) (how much memory you have) 3) How are you copying 500 MB of data. This matters as there are multiple ways of copying and it may be something about how you are doing it. It doesn't matter how much RAM your system has, once you copy more than 500 MB you will get stuff like Input/output error or just plain crashes like Segmentation fault.
