Description (partial)

ASA stops sending logs to the FTP Server randomly.

This only affects logging on the ASA when ftp-bufferwrap is configured. The following configurations are necessary:

logging ftp-bufferwrap
logging ftp-server {Server-IP}{Dir} {Username} {Password}

This issue occurs randomly. Examining a packet capture will show that the ASA can successfully establish the FTP Control connection but never initiates the FTP Data connection
