How to resolve "Too many open files" problem

When running certain software in your Linux environment, you may have come across the following exception, which is a process blocker.

/wso2/carbonstudio/eclipse/esb/mediator/impl/EnrichMediatorImpl.class (Too many open files)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
at java.io.FileOutputStream.<init>(FileOutputStream.java:131)
at org.ant4eclipse.lib.core.util.Utilities.writeFile(Utilities.java:1049)
... 95 more 


Sometimes these occur due to lack of some property setting in your machine.
If you too are fed up of tackling with those errors, follow the steps below for a fix.
  • Step 1
Go to /etc/security directory of your computer by the following command in your console
     cd /etc/security
  • Step 2
edit the limits.conf with following properties and save.
* soft      nofile   65535
* hard    nofile   65535Make sure that you do not comment on the above 2 lines. 
 
Problem Solved!! Now you can carry on your work.
