> What it may be? A connection lose? that'd be my first guess. it is, unfortunately, not uncommon for routers which do NAT (and some corporate firewalls) to close idle connections on you. i used to have a cron script that ran on the NATed system, cpu'd in, did the postroot, and then hung around running "date" every once in a while, which was sufficient to keep the connection open. i've lost that script, but it shouldn't be hard to reproduce.
