I make an application with Berkeley DB lib(4.4.20).I create a database
with DB_RECNUM flag. Which document say it will not support dup
items.It is Ok.But it run a few days later,I find some items with the
same key.Like below:
key data
1 data1
2 data2
2 data3
3 data4

May be the application was killed and restart before it met the
mistake.But i am not sure. And it is hard to recur.Why it make not
identical with the document and how to fix it? Please help me!
