#9749 new Bug report

SFTP never disconnects from server

Reported by: klam0 Owned by:
Priority: normal Component: FileZilla Client
Keywords: sftp disconnect processes Cc:
Component version: Operating system type: Windows
Operating system version: 8.1

Description

When connecting to the server using SFTP, the following two processes are created on the server:

UID PID PPID C STIME TTY TIME CMD
username 23563 23560 0 19:16 ? 00:00:00 sshd: username@notty
username 23564 23563 0 19:16 ? 00:00:00 /usr/lib/openssh/sftp-server

They remain active even after the connection closes (ie: disconnecting from FileZilla or closing FileZilla). The next time a new connection is invoked, those two processes are recreated, until they clog the process list.

Tested with FileZilla 3.9.0.2, on two Linux servers, one is CentOS 6.5, the other is Debian 6.0.6.

Using Cyberduck on the same machines, the processes disappear immediately when disconnecting.

Is fzsftp still running on the client machine even after closing FileZilla?

During SFTP connection, there are two fzsftp processes active on the machine. When closing FileZilla, they both disappear.
