SIPP: open file restriction> FD_SETSIZE

Actually I am trying to run SIPP 3.3 on opensuse 11 using the bash console with java. When I start SIPP with

proc = Runtime.getRuntime().exec("/bin/bash", null, wd);

... 

printWriter.println("./sipp -i "+Config.IP+" -sf uac.xml "+Config.IP+":5060");

error stream gives the following output

Warning: open file restriction> FD_SETSIZE; limit max. # open files for FD_SETSIZE = 1024 Resolution of the remote host 137.58.120.17 '... Done.

What does a warning mean? Is it possible that the bash terminal is freezing due to this warning? How can I remove this warning?

This means almost what he says ... The open file limit for each process ( ulimit -n) is greater than the predefined constant FD_SETSIZE, which is 1024. Thus, the program adjusts the open file access restriction down to match FD_SETSIZE.
