openssh unix dev - Oct 2004 - ssh-keyscan hangs in close_wait state

Hi folks  

I am running openssh-3.7.1 on my servers most of them are Solaris and Linux
built.

I run ssh-keyscan , some times it seems to be hanging ( even with -T option
enabled) in close_wait state.

can you please point me to any patch that is available or any work around for
this problem ?

thanks,
Sai.
