 You need to increase your maximum number of open files. You need to increase your maximum number of open files.

-To determine your open file limit, when logged in as the user Synchronet runs as, use the commands below. The hard limit is the systemwide limit, and the soft limit is one that a user can raise (up to the hard limit).+**Checking current open file limits**\\ 
 +The most reliable way to determine your open file limit is to login to your BBS as a sysop, run the '';SHELL'' [[module:str_cmds|string command]], and at the Linux command line use the commands below. The hard limit is the systemwide limit, and the soft limit is one that a user can raise (up to the hard limit).
  
 Soft limit: ''ulimit -Sn''\\ Soft limit: ''ulimit -Sn''\\
 Hard limit: ''ulimit -Hn'' Hard limit: ''ulimit -Hn''
  
-To alleviate the ERROR 24 problem on Linux, follow one of the following procedures.+**If you start Synchronet with systemd**\\ 
 +If you're using [[howto:systemd|systemd]] to start sbbs, edit your service file (usually sbbs.service) by adding the following line in the ''[Service]'' section:
  
 +<file sbbs.service>
 +LimitNOFILE=10000
 +</file>
  
-If you're not using systemd to start sbbs you can edit ''/etc/security/limits.conf'' to add the lines below.+After adding the line, reload the service file from the command line using ''systemctl daemon-reload''. Finally, restart Synchronet.
  
-To raise the soft limit up to the hard limit for your Synchronet user, it is recommended to add this line:+**If you start Synchronet manually or with a shell script**\\ 
 +If you start sbbs with a shell script, manually from the command line, or some other similar method, edit ''/etc/security/limits.conf'' to add the lines below.
  
-<file limits.conf> +To raise the soft limit for your Synchronet user, add this line:
-yourBBSuser     soft     nofile     unlimited +
-</file> +
- +
-If you are still receiving ERROR 24, try raising both limits for all users by adding these lines instead:+
  
 <file limits.conf> <file limits.conf>
-*               hard     nofile     unlimited +yourBBSuser     soft     nofile     10000
-*               soft     nofile     unlimited+
 </file> </file>
-  
- 
-If you are running sbbs from systemd then you'll need to edit your service file. Add the following line in the [Service] section 
- 
-   LimitNOFILE=10000 
-Reload the service file 
- 
-   systemctl daemon-reload 
-This will give you a safety net in case a runaway process tries to open a lot of files. Don't forget to restart your bbs after making the change.  
- 
-To verify the number of files, you can use the sysop ;SHELL command and run 
  
-  ulimit -a 
-to see exactly which limits your process is to conform to.
