Keith Wall updated QPID-7021:
-----------------------------
Description:
The BDB hot backup script may fail with the following exception.
The program is flawed in that it believes acquiring file handles for the JDB
files is sufficient to ensure that a subsequent *separate* open will succeed.
This is not true, at least on any UNIX like file system I have seen. Having an
open file e handle does not prevent another process removing the entry from the
filesystem.
