You definately want to upgrade to at least 1.1.13. There's a bug in 1.1.12 that prevents it from using more than 3GB (4GB?) of RAM, even if you specify 8GB. We had to upgrade for specifically that reason. However, if you're going to upgrade (which of course you are, otherwise you're wasting 6GB of the RAM in your servers), you may as well go to 1.2.2 to get the evictions. :) Anybody have any stability reports for 1.2.2? Paul recently suggested that 1.2.3 might be out very soon with some 'loose ends' wrapped up. Should we wait for 1.2.3 or go to 1.2.2 now? Or should we stay on 1.1.13 a little longer? -ben > cheers > Harry > > > On 5/31/07, Ben Hartshorne <[EMAIL PROTECTED]> wrote: > > > >but > >> every time I do a killall and reinstanciate them at a different size, > >then > >> do a reboot, the original size of 64 MB is restored.
