Automatic unloading of kernel modules

[Tarun_Thakur]

Hi all,

I would like to ask whether kernel modules that are loaded in kernel memory, but they are not getting used from long time, then in this case, what is the behaviour of kernel ? Does kernel unload modules or kernel modules remain in kernel memory until system is up ?

Please guide me.

Thanks and Regards,
Tarun

Hi Tarun_Thakur
Run command <lsmod> (discard brackets). This will give you a list of all modules in Memory at this time. The Linux Kernel is fairly adept at dealing with memory in an efficient manner. Not sure what you mean by "until system is up?", maybe you meant "until system goes down?". If memory is scarce I am sure that the Kernel deals in an appropriate manner to recover available memory space. It is one of Linux's strengths. Cheers...
