Issue/Introduction

When starting automatically Policy Server at machine boot time, the Policy Server reports only 1024 file descriptors instead of the 65k defined for the user smuser. Policy Server reports:

[1323/140645744498496][Wed Apr 29 2020 07:47:18][CServer.cpp:2646][INFO][sm-Server-01750] Maximum number of file descriptors available to this process is 4096
[1323/140645744498496][Wed Apr 29 2020 07:47:18][CServer.cpp:4847][INFO][sm-Server-02010] Available file descriptors: 1024

Automatic restart has been configured as per documentation (1).

Resolution

Some parameters can be added to the systemd configuration to solve the issue.

In the /etc/systemd/system/S98sm.service file, add the LimitNOFILE= parameter to the desired value.

To illustrate, wanting the process to have open files limit to 10000:

/etc/systemd/system/S98sm.service

  [Unit]
  Description=S98sm Service
  Requires=network.target

  [Service]
  Type=forking
  User=smuser
  LimitNOFILE=10000
  ExecStart=-/{home_policy_server}/start-all 
  ExecStop=-/{home_policy_server}/stop-all
  Restart=on-abort

  [Install]
  WantedBy=multi-user.target
