unable to work with eval

I have successfull upto

[root@localhost init.d]# ./sisp start
Starting sisp_amf:
At least one interface (eth0) has a low value for the "unresolved
neighbour queue length" kernel parameter. This may cause problems for
this application. See the evaluation kit release notes for more
information.

[ OK ]
[root@localhost init.d]#
[root@localhost init.d]#
[root@localhost init.d]#

after that it just hangs...
Nothing is logged in /var/log/sisp
If machine hangs, then we have to restart no other option including "ps -efwww | grep sisp".After restart i have executed ps -efwww | grep sisp but it shows no results.var/log/sisp also produces no results after restart.
Im only using eval model.I have just followed default installation steps for single node setup 2.1.
pls find me solution...
Pls do the needfull.
