Hi Preetish,
That shows that you have only 1024 file descriptors available on your system.
In my FreeBSD machines, I usually don't have to adjust file descriptors because the defaults are more than I need (7000 - 14000).

I guess you don't have the kern.maxfilesperproc variable.
What do you have for your kern.maxusers variable?
If nothing helps, you may have to re-compile your kernel with the following added parameter:
option MAXFILES=8192
But still, I think that there are other ways to increase your file descriptors besides re-compiling your kernel.
You can ask for help in the openbsd mailing list regarding your problem.

Reducing just the size of your cache may not be able to help you much with your file descriptors limit.

- From your above data, your service response times which are under 1.5 seconds are good figures for a satellite link. Before, it was 15 seconds! Considering that, your proxy server is much faster now. But since your data above is only 2 minutes old, you have to monitor in regularly for a longer period of time.
Starting with a cache_dir size of 10GB is good start. You can later increase it's size based upon your needs and demands.
Thanking you...
