Red Hat Bugzilla – Bug 25516
Installer doesnt turn on swap early enough on low mem machines
Last modified: 2007-04-18 12:31:02 EDT
During a text FTP custom install of Fisher beta-3, the following groups are selected. The dialog "Dependency Check" is then presented, and anaconda exits (no traceback option): "install exited abnormally -- received signal 15". Reproducible.

How much RAM is in your system?
48MB
Try booting the installer with the command: linux mem=32M You are running out of ram. We have a test to see if you have too little RAM, in which case we turn on swap. Currently this only happens at 34M or less. We probably need to move the little up. Let me know if that works.
Note to ewt - we want the loader to tell us how much space ramdisks are using so we can incorporate that into the decision to turn on swap early or not.
anaconda will now reduce the amount of memory in the machine by the amount of memory used by the ramdisks. We need to build trees to test this properly though. anaconda takes a --overhead option which the loader should be computing properly.
That's it! I got the "need to turn swap on" dialog this time. Thanks for the fast analysis.
This defect is considered MUST-FIX for Florence Release-Candidate #1
Needs to fix ewt's test.
Still run out of memory - probably need to bump up threshold for enabling swap early.
Need to have different criteria for text and gui installs too, since X eats ram.
Have not had any additional reports of problems. We fixed the GUI install to run in 48M w/o having to load swap early.
