Approximately 1 hour ago I encountered a serious problem. It was not life threatening to my system, however I believe that it probably did some serious wear to my SSD. The problem occurred while I was browsing through system preferences to customize expose and spaces (although that is not where this major leak started). After that I went to desktop/screen saver to check out each screen saver in Snow Leopard, watching each for a considerable amount of time (2-5 minutes each). During this time I decided to open up activity monitor because the screen saver graphics (particularly in flurry and arabesque) they started to lag. Activity monitor reported almost 3.98GB of ram being used with less than 12MB free. As well the page-outs were almost 5GB and swap being used (HD space to take the place as backup-ram) was over 8GB which would ware my SSD. I looked at system preferences in activity monitor and it showed that it was using 880+MB of ram, despite the whole system was using well over 10GB (including the swap of course). After quiting system preferences the issue was still 50% there so I restarted and it fixed the problem. However the fact remains that there is a memory leak somewhere in system preferences to do with viewing screen savers (possibly). Anyone else experience this? Better question I would like to know is, where can I report this bug to apple, as I would like to let them know (if they don't already) so that they can patch it.
