Java APIs

hi,

i am working with access database. the program is of updating a vast datbase
depending on the given input which goes under a big while loop and takes considerable time in updating the database. the problem is that in middle of updating i am getting message as
[Microsoft ODBC access driver][Too Many Client Tasks]

there absolutely no error in source because when i used postgres databse instead of access then everything was fine. i searched through all forums but couldn't find the soln. plz help me.

Thanx
