SSH daemon doesn't accept incoming connections
Hello,
I'm experiencing fairly weird issue when my linux box (running
Debian 4.0 powerpc) with the SSH server (SSH-2.0-OpenSSH_4.3p2
Debian-9) has stopped accepting incoming connections from a moment of
time without any obvious reason.
Any attempts to establish a connection fail before I'm being asked
for password.
Below is the verbose log of the failed session:

The problem still shows up even when I'm trying to connect to the server
locally by "ssh localhost".
The weird part is that all already established SSH connections to this
server work fine. Even the SSHFS mounted directory is still available.
I've been seeing this problem for the second time. The first time I did
reboot the server and it has helped.
I have googled for the similar issues but with no luck.
I can provide server configs if it makes sense.
thanks,
kuvkir
P.S. I'm not subscibed, so please keep me on cc.
