| |
Helo,
When I do varios disk read-write operations (ex.: copying some ISO from one partition to another), my RAM gets almost FULL. It keeps growing in usage during the read-write operation. But when the operation finishes, the memory keeps FULL, even after running a sync command. The swap isn't used in this case.
I think that UDMA uses a lot of memory without deallocing it.
Look: total used free shared buffers cached Mem: 772368 645884 126484 0 85072 393896 -/+ buffers/cache: 166916 605452 Swap: 1044188 0 1044188
I'm a newbie on kernel development, but I think that must be something related with the Linux kernel because I've tested a lot, in Slackware 8.0 and on my Linux-From-Scratch distro (I'm using now).
I compared to other OS and Linux is the only that does that, so it's not ahardware problem.
My computer is a:
Intem Pentium 3 EB 800Mhz MB ASUS CUV4X - BIOS 1009 Chipset: VIA Apollo Pro133X - NB: VT82C694Z - SB: VT82C686A 768MB DIMM RAM PC133 HD Quantum lct30 (30GB - 5400 RPM) etc...
Essential Softz Kernel Linux-2.4.18 GlibC 2.2.5 GCC 3.0.4
The .config of my kernel is attached to this email.
Please, help me to solve this.
Regards,
