I'm still having problems with a memory leak, and I can't seem to trace it down. I just upgraded to kernel 2.4.12-7 from Mantel's ftp and I'm running X 4.1.0-48, and KDE 2.2.1. Here's the problem: I have 512 MB physical memory in the machine. Immediately after bootup and logging in to KDE I have just over 300 meg free, according to 'free'. Right now, after having the machine up for little over a day, I have just over 60 meg free. I shut down X, just to see if it was that, but nope, the memory is still gone. Now, correct me if I'm wrong, but if I add up the memory usage in 'ps aux', not counting duplicate threads using shared memory blocks, and add that to the memory used by modules according to lsmod, aren't I supposed to get the total memory used by the machine? Well, that adds up to about 100 meg with X down. I can't find any trace of the remaining memory. my question is this: given the above, could someone tell me what it is I don't know about memory handling in linux. //Anders -- ICQ: 132715168 YM: cicerose
