I applied latest service patch 3282 to all the instances on qa box, and two of them failed to start after, got the errors:
Server TCP provider failed to listen on [ 'any' 23141]. Tcp port is already in use.
TDSSNIClient initialization failed with error 0x2740, status code 0xa.
I tried to change the TCP port number, but it didn't work, got the same error.
Wondering if anybody know how to fix this ? Thx.
