[jetty-users] Jetty 7.4.4 using 100% CPU (apparently in SelectChannelCon

[Tony Arcieri <tony@xxxxxxxxxxxxxx>]

Hi, seems like this is something of a long standing problem (JETTY-937) but we're seeing it on the latest release of Jetty. I saw this thread which appeared to be a similar issue with SslSocketConnector:

http://dev.eclipse.org/mhonarc/lists/jetty-users/msg01322.html

Our problems were much worse with Jetty 7.4.2. Jetty 7.4.4 seemed to improve things, to where we're seeing the problem far less frequently, but it's still there. Rolling back to Jetty 7.3.1 seems to have fixed our problems, AFAICT.

Here's a thread dump of one of our JVMs in the 100% CPU state:

All threads are blocked except Jetty's acceptor threads, which are consuming 100% CPU.
