Hi Corinna,

the following error was logged in the sshd.log :

2 [main] sshd 7140 d:\Sygwin\usr\sbin\sshd.exe: *** fatal error -
could not load user32, Win32 error 1114

I tried to google this but could not make too much sense of the error.
Its supposed to be a failure of a dll initialization.

And this occurs only after the sessions limit mentioned earlier are reached.
