Hello all,

B9 updated to latest running on a VMWare virtual machine with 1GB RAM +
512MB swap.
Running yum update dies on Updating: glib2 ...
error: Couldn't fork %post: Cannot allocate memory.

Okay so for x86_64 rawhide yum is going to use about 450-500MB of memory
for the package lists and depsolving.
Eeeek.
Are you expecting the same memory consumption under F9-release?

For the same set of packages, etc on a 32bit box the memory size is
112MB.

It's due to how python does 64bit objects in memory - they explode about
2-3x the size.


That may go to explain why I see "f9beta update takes forever"


James Antill has done some marvelous work reducing the overall memory
footprint of yum, but it's not going to overcome the 64bit issue above.

Unless there is a compelling reason like you're using > 4GB of ram, you
should think about running i686 not x86_64.

In my case
a) It's too late, I've been running 64-bit since this about time in the f8 cycle. b) I may well add RAM, I've already increased disk by an order of magnitude. I think my mobo supports eight, but only has two at present.
