Description
==========
BusinessConnect 5.3.X appears to be handling inbound transaction multiple times in a multiple engine environment when using the FTP transport.

Environment
===========
TIBCO BusinessConnect  5.X

Cause
==========
The file lock in the shared directory may be allowing multiple FTP pollers to execute on multiple engines.  Under normal operation, only one BC engine runs the FTP poller.

Resolution
==========
1). Stop all BC engines, and clear the checkpointing table.
2). Delete the flock as described in SOL1-BVK35L
3). Restart all BC engines.
