RE: Re: eth0: Memory squeeze, deferring packet

[<Rakupathy_Somasundaram@McAfee.com>]

Hi  Michael Loftis,

Thanks for your reply.

I noticed few things from the free command.

When the system starts up the cached is 115 Megs and free is 50 Megs.

When this memory squeeze problem happens the cached has increased to 170
Megs and free has gone down to just 2 Megs.

Why is the kernel cribbing instead of using the cached memroy ( i.e.,
running the garbage collector to move some memory from cached to free )
? Is there a way to control the max limit for caching ? Say I want to
restric the max cached to 50 Megs? i.e., don't cache anymore if the
cached usage has increased to 50 Megs.

Thanks,
Rakupathy.

Wow, this message and it's problem are...ancient.  October *2001*.
2.4.27 is current in the 2.4 series.  I'd try upgrading your kernel
first.  Or making sure you have some swap setup so the kernel is a
little less likely to get into these sort of memory pressure issues.
