Well, it seems like you start two nodes on the same host, and as first node occupies default thin client port (10800) the second node takes the next one (10801).
I believe you use 127.0.0.1 or something like this for your thin client host lists which effectively means 127.0.0.1:10800. So, your thin client just is not aware about the second node which is using 10801 port once the first node is dead. To fix it you can write a second address in your client configuration: 127.0.0.1:10800,127.0.0.1:10801 or simply 127.0.0.1:10800..10801. Hope, it helps.
