There was a master and a slave.
I added 20000 xml documents to a container of master's environment and every thing was running ok,
the new data transferred and the slave's log updated.
After a few minutes all data were replicated to the slave and there are tow log files: log.0000000001 log.0000000002.
But when i restarted the slave program. the "log.0000000002" disappeared. It take a few minutes as long as before to transport the data and logs. Restart again ,repeat again. I had never changed the master's data after that 20000 xml documents.
The more documents added, the more time was token to replicate when restart.
(In the slave program i opened environment and didn't open other resource. when the slave exit, I closed the environment.)
Why the log disappeared when I restart the slave and how to deal with it?
