Cisco Bug: CSCtf28762 - User abort during FTP file transfer causes connection hang
Nov 01, 2010
- Cisco ACE 4700 Series Application Control Engine Appliances
Known Affected Releases
Symptom: User abort during file download (active FTP) resets the control channel and leaves the data-channel unusable. The remote end-points enter retransmission because they consider the data-channel to be alive and get stuck. Conditions: According to the RFC 959, certain commands (such as ABOR, STAT, QUIT) may be sent over the control connection while a data transfer is in progress. Some servers may not be able to monitor the control and data connections simultaneously, in which case some special ABORT sequence will be necessary to get the server's attention.
