Graylog Server RPM - file descriptor limit #72

Closed coffee-squirrel closed 7 years ago

coffee-squirrel commented 7 years ago

Expected Behavior

Installation of the RPM should result in the same file descriptor limit being used as other packages (see e8e0549ed514d29b31e0f2d573a13ef5d5290a13).

Current Behavior

The default file descriptor limit (4096 in my case) is used when the RPM is used for Graylog Server installation.

Possible Solution

Add ulimit -n 64000 inside the start function (before the daemon call) in "fpm-recipes/recipes/graylog-server/files/rpm/init.d".

Steps to Reproduce (for bugs)

  1. Have a CentOS/RHEL system
  2. Install a Graylog Server RPM (e.g. "graylog-server-2.0.3-1.noarch.rpm")
  3. Verify the graylog-server service is started
  4. Get the current limits (sudo cat /proc/graylog_server_PID/limits) and note "Max open files" is the default (e.g. 4096)
  5. Stop the graylog-server service
  6. Insert ulimit -n 64000 as the first line of the start function in "/etc/init.d/graylog-server"
  7. Start the graylog-server service
  8. Get the current limits (sudo cat /proc/graylog_server_PID/limits) and note "Max open files" is now 64000

    Context

We were seeing "Too many open files" in the Graylog Server "server.log" and wanted to increase the limit to rule that out.

This will be fixed in the upcoming Graylog 2.1 release. Thank you for the report!
