Hi all,
I am wondering if it is normal for the server to have a
large number of file descriptors open simultaneously and
if it actually closes them when it is done with them.

After putting some files up on the server and getting some
hits (probably max of 5 simultaneous clients) I started
seeing the following exception when attempting to connect
to the server:
java.net.SocketException: Too many open files

The max number of open files per process was 110.
I bumped this up to 256 and haven't seen a problem
yet, but was wondering if this number of open files
would be expected.

I have included the complete exception stack traces
from two example exceptions below.

Thanks!
Shawn

PS: Thanks for the .shtml answers.  I thought that was
what I needed to do, but was a little too unsure of my
knowledge of Jigsaw to happily delete the html extension
and recreate it.
