Memory Issue(Red Hat Linux 2.4 kernel)
Can u tell me anyone , why free memory rapidly decrease in Red Hat Linux 9.0 with 2.4 kernel. (As I saw
via free -m).
Suppose free memory becomes 1 MB after some time,
and application want to do some stuff which requires more memory then how's system behave.As lots of technical article suggests,the system will use the memory from cache if it requires.
I am running a linux C++ application(GUI BASED QT-Programming) on a system , which runs in a foreground. This application want to run lifetime without interruption. When start to run the application, free memory is something 32MB free(128MB RAM) .
After 4-5 days memory becomes 1 MB free ,
application becomes slow and hangs after some time.
Why its happening??? As I checked the application via various memory tools and not observed any memory leak. One important thing is, memory
not allocated dynamically in application..
Thanks in advance....

Although RH 9 could be considered as an old linux system it's very strange that free memory decreases dramatically.
Try to monitor your app with top and keep track of the processes that take more memory. Maybe 128 MB is not enough to run RH 9 with that application.
