Hi George,

this is still strange: 80 % of the ftp calls are correctly executed, one
fifth is not. I am sitting behind my private "Fritzbox! 6340 cable"
router with a single PC attached to it. The internet provider is
Kabel-BW. 

I had been thinking about a timing problem in tlmgr. What do the others
think?

Greetings from the Black Forest!
