Our customer configured external repository for some document class on FTP server. Normally it works fine but time to time he faced randomly error message:
There is no any errors in logs on FTP server side. Sometimes in j2ee logs below error occurs. I am not really sure it is related to connection with FTP

java.lang.IllegalStateException: The connection has been closed.
Does anyone know what could be the problem? Any timeout or network issue?
