The document I am refering to is :
/usr/src/linux/Documentation/memory-tuning.txt
I used to get alot of "UDP" out of free ports error messages. Until, I increased
my pagefile size.
ie :

There are several files in /proc/sys/vm you can use to tune the
memory system with.
You inspect them with 'cat', and set them with 'echo'. For example,
/proc/sys/vm/freepages:
'# cat /proc/sys/vm/freepages' may yield:
64 96 128
These three numbers are: min_free_pages, free_pages_low and
free_pages_high.
You can adjust these with a command such as:
# echo "128 256 512" > /proc/sys/vm/freepages
Free memory never goes down below min_free_pages except for atomic
allocation. Background swapping is started if the number of free
pages falls below free_pages_high, and intensive swapping is started
below free_pages_low. A "page" is 4 kB.
The values selected as boot defaults are the following: For a
machine with n>=8 Megabytes of memory, set min_free_pages = n*2,
free_pages_low = n*3 and free_pages_high = n*4. Machines with
8 Megabytes or less behave as if they had 8 Megabytes.
If "out of memory" errors sometimes occur, or if your machine does lots
of networking, increasing min_free_pages to 64 or more may be a good
idea.

I followed these recommendations, and its working fine now. I didnt need to
adjuect my timeouts at all.
