Modified memory leak? - Windows 7

post #1 of 15
Thread Starter 

No programs open....

I have a memory leak that is hard to trace for a few reasons:
1. It leaks so little that i can only notice it increased substantially after 1 day
2. it fills 'Shared memory' aka paging files aka modified memory
3. its on a work computer where i have to run my environment .. so i dont have much opportunity to eliminate programs one by one.

The leak does something like 2GB a day, so after 5-6 days ... my memory is stuffed.... as per the screen capture above. The screen was taken AFTER all programs were shutdown after a 5-6 day running period, so no program cleans this up after closing. I am forced to restart


Now i've tried monitoring for leaks, but since it takes so long i havent found a good method yet......so what im asking is has anyone had this happen to them before? if so....how did you resolve it. if not, does anyone know effective memory leak capturing methods?

Have tried:
Sys internal tools
Performance monitor - graphed paging files for all processes, ran it on an hour interval (too fast, next would be day intervals)

Yup, sysinternal will find it; might try 12 hr intervals.

Like i said in my initial post, it did NOT work. I tried both rammap and vmmap, none of them attribute the extra paging files to any application.

Hmmm, I'll look at this tonight -- at work now. I'd suspect anything recently installed.

RAMMap will find it, it just won't be easy. Snap the report looking at the Processes tab every few hours and start comparing each report to the previous to see which process is creeping up and looks suspect. Again, its probably something installed or modified soon before you noticed the problem.

I have seen memory leaks running MATLAB. Figured out the culprit program because that was the only program being used. Killing the process does NOT really recovers the leaked RAM. The only way i know to recover is by restarting Windows.

Deal is ... with this method after 24 hours theoretically i'd be able to see what program has 12GB of memory used up.... but that is not the case... unless there is some very specific way that im unaware of.... i've not seen any trace of the 12GB being attributed to anything particular application

I've had a similar problem before, turned out to be audiodg.exe. Might be worth a look.

In your case, were you able to see the memory increase in task manager?

How did you discover it being the problem?
