FTP server keeps crashing after several days runtime

[elmar]

Hi all,

we are using Core FTP Server 2.0, build 637, 64bit.
The server is running on a dedicated machine, 24/7, with a large number of logins/logouts (every few seconds), but little file transfer activity.
We are observing server crashes every few days.
The last line in the log file is "winsock error 10053", the previous lines are just showing the regular FTP activities, but no error indication at all.
We are noticing this issue already since several software versions.
See below for the information found in the Windows event log.
Is there any way to generate additional debug information ?

Best regards

Elmar

Make sure your "max conns per IP" is set at only the maximum you require (anything more than 5 is questionable).

if there is a coredump.log in the installation or %temp%, send it in to feedback

Build 642 and greater should resolve this issue.

We're having the same issue with 2.0, build 668, 64-bit. Core FTP server process (not the one started via service, but the other one) crashes every now and then.
