[Disclaimer: I'm a newbie.] I was closely monitoring the memory usage on my system while testing something. I decided to run updatedb to try to make the system less responsive and see if a realtime program would hold up. For no apparent reason, while updatedb was running free(1) reported that the memory in use (+/- buffers/cache) was skyrocketing steadily. Looking at the process lists, no application was anywhere near the 95mb that the used memory had risen by. After the updatedb process had completed, the memory in use stopped climbing but it never went down below the 95mb that the memory usage had exploded by, even after killing X and just about every process. I have seen similar situations occur with various 2.4.0-test kernels. Even dropping down to single-user mode still reports that a lot of memory is in use, and no process is anywhere near large enough to be a significant part of it. The system is an Athlon with an IDE disk drive and an ext2 filesystem on that drive. I can provide further information if would be helpful.
