Too Many Open Files?

Hi all,

We have a system that tanked last night, reporting:

14-Aug-2016 19:13:57.440 SEVERE [http-nio-8080-Acceptor-0]$ Socket accept failed Too many open files

at Method)





Any ideas what the cause might be? The environment is Ubuntu 14.04, Tomcat 8, Java 8.

A cat /proc/sys/fs/file-maxreturns6556412 – and that system was physically restarted within the last week. I find it hard to believe that the web server would have 6,5 million files open in such a short period of time.

War is 2.23

OS is Ubuntu 14.04 LTS

Tomcat 8

Java 8

Kind Regards,

Jason Phillips
