Red Hat Bugzilla – Bug 25895
sort in textutils-2.0.11-2 is broken
Last modified: 2008-03-13 15:18:51 EDT
# echo foo | sort
sort: memory exhausted
I can't reproduce this on any machine.
Are you sure it's not just what it says, out of memory?
It turns out that the bug is the usage of
which returns a number which may not be available to a single
process on a 32bit system with 4GB RAM. In my case,
it returns 3.8GB. It is the total free memory on my machine.
But it is the usable memory for a single process.
I am using a patch like this. It seems to work on my 4GB machine.

This defect is considered MUST-FIX for Florence Release-Candidate #1
Should be fixed in textutils-2.0.11-4. Thanks for the patch!
