Hi Folks,
I've been noticing a lot of errors being reported on my FTP server
console lately. Every 5 minutes, the FTP server wakes up and attempts
to do "something" that fails and generates multiple error messages. It
seems to issue one DTCFTS2512I for each record in FTP BANNER, for
example here is the console log from an unused FTP server that has a 1
record FTP BANNER:
10:34:50 DTCFTS0021I Server-FTP: Initialization completed 10:34:50 EDT

10:56:00 ion
10:56:00 DTCFTS2512I Error completion on #1: No such connection
The "Error completion on #" starts at 0 and increments to 2 and then
restarts at 0 consistently.
Tracing FTP doesn't provide a heck of a lot of useful information:

Erasing the FTP BANNER file makes the problem go away (but we MUST use
an FTP BANNER, it contains certain text we are required to display for
any/all network connections....).
Does anyone have any idea what's going on here? What "foreign host" is
it trying to connect to?
