Возникли проблемы с загрузкой ZK SDK-не удается получить весь файл журнала

---

Dear Sir, 
iam writing a windows service to get attendance log from attendance machine ,  iam using Visual Studio 2015 
and iam working on windows 10 64 bit  , the refence file name  is ZKEUEmKeeperNet.dll  version 1.0.0.0
runtime version v2.0.50727  actually iam facing 2 problems : 
 
1- iam getting partial log : i mean not all punch transactions appear (iam taking this data to DB Oracle )!!!!
i tried  i do not know why  but iam  removed the DB connection code and trying to write the data directly to harddisk  using writetofile function
 
2- iam not getting the log file on harddisk this is not an sdk problem as i think  this problem happened recently i do not know why!!
 
 any suggestions for this problem or is the database connection with orable caused a problem or the Onstart service time caused a problem iam running the service every 10 seconds and if i increased the time  problems happen like if  i make it every 100 seconds , please i need support it is taking too much time , thanks in advance
