Issue/Introduction
We're starting automatically Policy Server at machine boot time and we
see after a machine reboot, the Policy Server reports only 1024 file
descriptors instead of the 65k we have defined for the user
smuser. Policy Server logs report :
[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

07:47:18][CServer.cpp:4847][INFO][sm-Server-02010] Available file
descriptors: 1024
We've followed indications here to configure automatic restart :

How can we fix that ?
Environment
Policy Server 12.8SP3 on RedHat 7;
Resolution
At first glance, you can add some parameters to the systemd
configuration to solve the issue.
In /etc/systemd/system/S98sm.service files, add the LimitNOFILE=
parameter to the value you desire.
To illustrate, if I want 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=-/opt/CA/siteminder/start-all
ExecStop=-/opt/CA/siteminder/stop-all
Restart=on-abort
[Install]
