Ronaldo,

We got around this problem by putting this entry in the .profile for the
user running Glassfish (on an AIX server):

  ulimit -n 20000

'ulimit -n' sets the maximum number of file descriptors for the user.
We had 10 instances of Glassfish running on the server, so we had to set
the value quite high (default is 1024).
