Piranha hangs

[Ritesh Agrawal]

Hi ,
   i am facing strange problem in implmenting load balancer using 
piranha,  i make loadbalancer LB1 with following configurations
LB1:
private ip: 192.168.35.253
public ip:192.168.24.126
floating VIP:192.168.35.254
service ip : 192.168.24.60

and spam2 is my real server  with ip 192.168.35.22 providing http service.
after staring pulse, when  i send  the request from outside world to 
192.168.24.60:80. it works fine,but after some time my LB1 hanged 
displaying no error no clue,
unable to find the proper reason of hanging.
