 +===== Recycle =====
 +**Question:**\\
 +Why do my servers/services fail to recycle when I set the node-recycle flag (e.g. saving changes in [[util:SCFG]]) or when touching recycle [[config:semfiles]]?
 +
 +**Answer:**\\
 +Servers will not recycle while they are in-use.

 +**Question:**\\
 +What do the following warning-level log messages indicate?
 +  Disabling Terminal Server recycle support
 +  Disabling FTP Server recycle support
 +  Disabling Web Server recycle support
 +  Disabling Mail Server recycle support
 +  Disabling Services recycle support
 +  
 +**Answer:**\\
 +Recycle support can be disabled manually be setting the ''NO_RECYCLE'' ''Options'' flag in one or more server sections of your ''[[config:sbbs.ini]]'' file.\\
 +The log warning messages above ("Disabling ... recycle support") indicate that the BBS automatically set the ''NO_RECYCLE'' option flag because it was:
 +  - Configured to bind-to/listen-on TCP ports < 1024 (the so-called "reserved" ports)
 +  - **and** the BBS was configured to change the current user-id in the ''[[config:sbbs.ini#UNIX]]'' section of ''[[config:sbbs.ini]]''
 +  - **and** the BBS could not dynamically set the bind capabilities using the Linux "Capabilities" syscall interface.
 +
 +The solution is to remove the ''User'' and ''Group'' settings from the ''[[config:sbbs.ini#UNIX]]'' section of ''[[config:sbbs.ini]]'' and then follow the instructions [[howto:Linux_non-root|here]] for running the BBS on Linux as a non-root user (if you haven't already).
 +
 +===== Maximum Open Files =====
 +**Question:**\\
 +Why am I seeing ''ERROR 24 (Too many open files)'' failures in my error log?
 +
 +**Answer:**\\
 +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 a soft limit that a user can raise (up to the hard limit).
 +
 +Soft limit: ''ulimit -Sn''\\
 +Hard limit: ''ulimit -Hn''
 +
 +To alleviate the ERROR 24 problem on Linux, edit ''/etc/security/limits.conf'' to add the lines below.
 +
 +To raise the soft limit up to the hard limit for your Synchronet user, it is recommended to add this line:
 +
 +<file limits.conf>
 +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>
 +*               hard     nofile     unlimited
 +*               soft     nofile     unlimited
 +</file>
 +
