Hi
Since updating some plugins we are getting lots of "Too many open files"
warnings. Here's an example:
Apr 12, 2017 9:38:35 PM WARNING org.eclipse.jetty.util.log.JavaUtilLog warn
java.io.IOException: Too many open files
at sun.nio.ch.ServerSocketChannelImpl.accept0(Native Method)
at
sun.nio.ch.ServerSocketChannelImpl.accept(ServerSocketChannelImpl.java:241)

org.eclipse.jetty.server.ServerConnector.accept(ServerConnector.java:377)

org.eclipse.jetty.server.AbstractConnector$Acceptor.run(AbstractConnector.java:500)

at
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
at java.lang.Thread.run(Thread.java:745)
I know that there is a File Leak Detector plugin but such investigation seems
quite involved.
On the master, we have:
$ ulimit -a
<snip>
open files (-n) 1024
Should 1024 be sufficient? Do I need to worry about limits on the slaves?
Any other suggestions please? I don't know why these warnings have suddenly
appeared.
Best regards
David
