We have deployed our application on rhel 7 from rhel 6 and after deployment we are seeing following error in the catalina.properties, due to this my vm link is getting down frequently. We are using Documentum CMIS 16.4 version on tomcat 8.5 version.

Following is the error's details:

27-Nov-2018 01:57:00.536 SEVERE [https-jsse-nio-0.0.0.0-12510-Acceptor-0] org.apache.tomcat.util.net.NioEndpoint$Acceptor.run Socket accept failed
 java.io.IOException: Too many open files
        at sun.nio.ch.ServerSocketChannelImpl.accept0(Native Method)
        at sun.nio.ch.ServerSocketChannelImpl.accept(ServerSocketChannelImpl.java:422)
        at sun.nio.ch.ServerSocketChannelImpl.accept(ServerSocketChannelImpl.java:250)
        at org.apache.tomcat.util.net.NioEndpoint$Acceptor.run(NioEndpoint.java:457)
        at java.lang.Thread.run(Thread.java:748)

Here are my efforts in order to solve this problem: I have increased ulimit value from 1024 to 8192 for specific user and rebooted it, recycled tomcat service but nothing happened. I had done changed to file named /etc/security/limits.d/20-nproc.conf/20-nproc.conf. kindly help here.

我没有添加评论的权限，所以发布作为答案。尝试使用命令找出打开了哪些文件 lsof -p <pid> | wc -l。

这将告诉您哪些文件没有关闭。您还可以通过以下方式检查正在运行的进程的限制 cat /proc/<pid>/limits
