configuration problems on LTM 3600

hi,there! i met a tough problem on LTM configuration recently.

i need to configure a LTM to make it worked with one server which was opening two port 8016 and 8023,i call it server A in this case .

network configuration

first of all, i created a server vlan 137 and a external vlan 125 on LTM,both of the two vlans and their gateway existed on the Switchs which was connecting to LTM , then i configured a self ip of server vlan 82.201.37.250.one other self ip of external vlan 82.200.125.1,a default route ,next hop was external vlan.

local traffic configuration

i added the server IP as the nodes ,and the healthy monitor was icmp, then i had them joined into a pool which named server_poolA, server A's Ip address was 82.201.37.42 and its port was 8016 ,another port was 8023,and the state of the pool was green .

i configured a vs which have the same ip address to the ip of Server A 82.201.37.42 ,the port of the vs was 8016 .then i configured the default persistence profile as source_addr,the SNAT as Automap, the pool as server_poolA,the connection profile as oneconnect profile.

i thinked it should work well at first,but it was out of my prediction,when i login into the server with http://82.201.37.42:8016 but it was always playing a joke with me ,sometimes it works well, but sometimes the broswer can not open the server.

question

could someone please help me to find out the problem on my configuration . thanks.

can i set a ip address of a vs to has the same ip to a pool member?
