attached code runs normally when access a single mongo server(NOT a replica set )
but when i try to access replica set server, it pop a exception:(40 thread test)
java.lang.IllegalStateException: can't authenticate twice on the same database
i don't know why [m_DBAccess.isAuthenticated()]returns a false and [m_DBAccess.authenticate] pop this exception.
please help.
PS:
This only appearred in win 7 server(env 1), it does not appearred in linux server(env 2)
code backgroud
m_MongoDB is a static Mongo instance.
m_DBAccess is a DB instance that every thread will get a db instance by using [m_MongoDB.getDB("db_image")]
In my opinion, every thread has a different db object (although it point to the same db), so authentication of each thread is needed.
Am i right?
