OutOfMemoryError when clients disconnect without issuing a QUIT command.
------------------------------------------------------------------------
Key: FTPSERVER-116
URL: https://issues.apache.org/jira/browse/FTPSERVER-116
Project: FtpServer
Issue Type: Bug
Components: Core
Reporter: Magnus Lind
I have done some memory profiling regarding this problem:
The class org.apache.ftpserver.listener.ConnectionManagerImpl stores all
connections it ceates in its conList member variable.
Normally the connection is removed from conList when it is closed. However,
this is only the case if the client issues a QUIT command before closing the
connection.
Connections for clients that don't issue a QUIT command before disconnecting
are left in the conList variable and never removed.
As far as I understand, It should be ok to disconnect without issuing a QUIT
command.
When enough connections are left in the conList variable the jvm runs out of
memory.
