Hi Minh,

I found a function checkNtfServerState() that read the global ntfa_ntfsv_state 
variable. This function does not protect the variable with a mutex. The 
corresponding  ntfa_update_ntfsv_state() is called when mutex is locked but the 
checkNtfServerState() is not, this is not thread safe.

Regards
Lennart
