This has nothing to do with the amount of inactive memory, this would be the result of a program leaking or consuming large amounts of resorces that it didnt need.. Have a look at the memory usage of your programs when they are first started and then compare that to the usage of when you notice the downgrade.. You will probably find something is using huge amounts of memory.. Thats a bug in the program most likely and you should report it or upgrade to a newer version or switch to a different program that does the same thing.. If you MUST use that software you could set a cron job to kill the process and start it again every few days or whatever you think is needed so that memory is released... Unlike windows you dont need to reboot to salvage leaked memory! > I've read the article about the VM design, and it is like you say, but, the > overhead on memory allocation from inactive memory, instead of free memory, > must be very high, that's the only way to explain the situation above. Inactive memory is not a bad thing! Where do you get this idea that free memory is better than inactive??
