Apologies if you already know this. The system use memory both for running programs and for file buffer cache. Sometimes a program requires memory that the cache is using - this is memory pressure. The relief is when the cache's are cleared and memory free'd up for programs. > ...is this just a perfect storm - clam, tracker... or is this problem > specifically Evolution related? > It's probably a combination of a number of things - tracker can use a lot of memory and it, of course, accesses disk, so creates cache. If clamd is scanning a big file, especially an archive, it too can be a significant consumer of memory. Evolution can also chew memory - I've seen it for some (HTML) messages that have a complex structure; the last time it happened was because some nice person sent me a Gb size message (kill evolution, start without preview, delete message, shout at person). If you receive an over-size message that clamd is trying to scan, tracker is trying to index and Evolution trying to display, then your system might become a little sluggish. I think your plan of upgrading to F32 (do it, it's much nicer!) and seeing if the problem recurs is the correct course of action.
