Hi Victor Thanks for your answer – I will try increasing the limits as they suggest.
Best regards David From: Victor Martinez [mailto:[email protected]] Sent: 13 April 2017 09:24 To: Jenkins Users <[email protected]> Cc: David Aldrich <[email protected]> Subject: Re: Too many open files Hi there, You could read the below blog entry: - https://support.cloudbees.com/hc/en-us/articles/204246140-Too-many-open-files Although it's the cloudbees support page, but it's the same core in the end. In my case, # ulimit -a .... open files (-n) 65536 ....

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) at org.eclipse.jetty.server.ServerConnector.accept(ServerConnector.java:377) at org.eclipse.jetty.server.AbstractConnector$Acceptor.run(AbstractConnector.java:500) at winstone.BoundedExecutorService$1.run(BoundedExecutorService.java:77) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$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.
