Like already said in the title, a large set of applications is suddenly having massive memory leaks. These are all programms that I have use for some time already, and none of them had this problem before.
At first I only noticed it in Firefox. It was suddenly becoming unresponsive even though I had nothing opened aside it. I thought nothing of it untill a started a game (Crusader Kings II) which normaly loads in about a minute or two on my system, but it kept loading and loading. A quick look at the taskmanager told me that it was indeed doing something, slowly but surely allocating more and more memory. I killed it at 600 MB, because it was getting nowhere.
I think it is plausible for this game to hold so much memory, but it had merly finished the first loading step at that time and was still chewing on the second one after about two minutes. Same thing with a lot of other games from different publishers, so I think it is a system level problem. Maybe a corrupted system memory allocation rutine, maybe in some windows API or something? How would I identify such a problem?
-Most progams don't seem to be affected by it, mostly games, especially all Paradox Interactive games and some others
-I am not sure that it is really a memory leak, as all affected programs are memory hungry and I don't know how much they actually need. However, if it is not a memory leak, it must be that the allocate memory too slowly, because a lot of programs have a noticably longer startup time (firefox sometimes even multiple minutes, windows media center a few seconds) or have sigificatly higher latency (CKII) even though the CPU usage is quite low
-Yes I know a lot of problems dissapear when you restart, but restarting was the first thing I did when CKII didn't start properly. Waiting one day and restarting today didn't fix anything either, thats why I am asking this
-Intel Core i5-3570K @ 3,8 GHz (so no overclocking issue)
-8 GB RAM
-NVIDIA GeForce GTX 680
-Windows 7 64 bit
-Built by myself but fully functional more than a year, I don't suspect any problems here
