Hi Guys,
We are running jetty5 on approximately ~50 server upwards. Mostly there are
more than 40 virtualhosts on a machine.
Now we have a 100% cpu-usage on two of this servers. We already switched the
hardware to virtualisation and now I replaced all regulary programfiles from
files of a working server.
Through ps -eLf and jstack I found the following (never ending) Thread:
"SocketListener0-7" prio=10 tid=0x0000000001eb7000 nid=0x5d7a runnable
[0x00007f569b2fc000]

What can cause this?
I know, jetty5... Upgrading and so on. We work on it. We made a mistake ealier,
integrating jetty too deep into our software...
Best regards & Thanks
