The route table intermittently loses all routing information, resulting in "Network unreachable" errors. Normally things work fine, and my ASDL modem connected via ethernet is problem free. Running the "route" command gives this:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 * 255.0.0.0 U 0 0 0 eth0
default 10.1.1.1 0.0.0.0 UG 0 0 0 eth0

But often (say 70% of the time) about 30 seconds after starting Azureus the route table is empty. All network communications fail, including pinging my modem. Azureus is not running as root. It should not be able to clear the route table.

The problem typically remains for one to five minutes, and then everything starts working by itself. The route table gets its entries back. On some occasions the problems appear to persist for hours (e.g. often during overnight downloads). Stopping Azureus always seems to fix the problem within a minute or so.

Azureus seems to be the only app I can find that triggers this issue. But clearly it is not a bug in Azureus, since it should not be able to affect the route table.
