ERROR 10055

Hi everyone,

I'm having a problem and hope someone can help me.

I'm using Core FTP LE on a windows server 2003 computer.

I need to upload some files everyday to a server, and for doing that I have a script scheduled to run everyday at the same time.

It was working fine until some days ago and I don't know what happened.

Since then it works one day and the next day I get error 10055:

Connect socket #-----------...Can't establish connection --> ------------:21 @ Tue Feb 15 08:15:04 2011
(10055-19) An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.

When rebooting the computer the problem is fixed until next day.

Does anyone know what could be happening?

Thanks in advance.

I haven't seen this issue before but it sounds like a resource error.

It's very possible that something outside of Core FTP is utilizing a large amount of winsock and/or system resources, and none are available when you see this message.

I did a quick search and brought up some MS patch issues related to this problem.
