memory leak in vsftpd

[Andreas Gocht]

Binary package hint: vsftpd

The ftp server vsftpd seems to have a memory leak.
When i'm connecting to my vsftpd server, with the tool kio-ftps (used in Dolphin) and the command "ftps://<email address hidden>", grows the memory usage (1 or 2 MB/s). If I stop the vsftpd server, the memory usage will fall.
I think this is a problem of wrong login. The kio-ftps tool hasn't asked for a password.
In the Logs there are up to 14 connects per second.
I'm using ubuntu 10.04 server (Ubuntu 10.04.1 LTS).
Version of vsftpd is 2.2.2-3ubuntu6 0

Thanks for reporting this bug and helping to make Ubuntu better. Could you tell us

1. if you stop the client, does the vsftpd memory usage go back down?
2. is there anything interesting in the vsftpd log files?
3. does the connection succeed if you use 'ftps://name:<email address hidden>" ?

We'd like to figure out what's causing this bug for you, but we haven't heard back from you in a while. Could you please provide the requested information? Thanks!

Sorry for time i needed.
If i closed Dolphin the memory usage do not go back down, but if I kill kio_ftps.

In the logs are many connects from my IP. 9 per second +-.

The login with user:<email address hidden> don't work.
