help with pfiles output

I deployed my application on a Weblogic 10.3 which is installed on a solaris. After a while I began to see "Too many open files" exceptions which yields to numerious problems. I took a pfiles output and nearly all the output is filled with lines which are similar to these:

1489: S_IFCHR mode:0000 dev:299,0 ino:51621 uid:0 gid:0 rdev:202,1966

Do you have any idea what these lines are trying to tell us?

Note: As requested in comments, I added "ls -li /devices/pci@7c0/pci@0/network@4:bge0" output below:

# ls -li /devices/pci@7c0/pci@0/network@4:bge0

Looks like your application is opening sockets that it never closes. Check your app.
