Short outage today

Due to an unknown reason antville.org was not reachable between ~10:15 and ~12:40 CET today.

(And a reboot of Elise was the only way to bring it online again...)

Update: It happened again (18:30–19:30h), but at least no reboot was necessary. This time it was enough to restart the Helma process.

However, some shit hits the fan here. I am pretty clueless. There are some obscure log messages in helma.server.log; could it be someone is trying to exploit a bug in Jetty or the Java Runtime?
