close connection, closeAllConnections()


For windows2000 and windowsXP, R.2.6.1
I have a little problem with the following lines

> socketConnection('', port=7496, server=F, blocking=F,
open='wb', encoding='');

        description              class               mode 
text             opened           can read
"->"           "socket"               "wb" 
"binary"           "opened"              "yes"
          can write

> showConnections(all=TRUE)
description class mode text isopen can read can write 0 "stdin" "terminal" "r" "text" "opened" "yes" "no" 1 "stdout" "terminal" "w" "text" "opened" "no" "yes" 2 "stderr" "terminal" "w" "text" "opened" "no" "yes"
3 "->" "socket" "wb" "binary" "opened" "yes" "yes"
> closeAllConnections()

Erreur dans close.socket(getConnection(set[i])) : invalid 'socket' argument

with the previous R version,
calling closeAllConnections() did nicely close connection #3 ... but now, this works no more.

I'm missing something and would be very thankful for any infos/pointer about this little worry.
(I believe some changes were planned with the connection functions in R.2.6.1, could it be that ?)
