 **Question:**\\ **Question:**\\
 How do I work around SDL_main errors (e.g. ''No protocol specified'' followed by a ''segmentation fault'') that prevent Synchronet applications (e.g. [[util:SCFG]], [[util:EchoCFG]], [[monitor:umonitor]], etc.) built with SDL 1.2 from running? How do I work around SDL_main errors (e.g. ''No protocol specified'' followed by a ''segmentation fault'') that prevent Synchronet applications (e.g. [[util:SCFG]], [[util:EchoCFG]], [[monitor:umonitor]], etc.) built with SDL 1.2 from running?

 **Answer:**\\ **Answer:**\\
-Clean re-build all of Synchronet without SDL support (include ''WITHOUT_SDL=1'' on the ''make'' command-lines) or set the ''SDL_VIDEODRIVER'' environment variable to the value of ''dummy'' (e.g. ''EXPORT SDL_VIDEODRIVER=dummy'') before executing the programs.+Double check that you can run X applications (e.g. ''xterm'', ''xeyes'') and if you cannot, you may need to grant X access to other user accounts with a command like: 
 +  xhost +SI:localuser:<username> 
 +executed before switching to another user account (e.g. with ''su'' or ''sudo''). 
 + 
 +Work-arounds: 
 +  - Clean re-build all of Synchronet without SDL support (include ''WITHOUT_SDL=1'' on the ''make'' command-lines or in your ''localdefs.mk'' file) 
 +  - Set the ''SDL_VIDEODRIVER'' environment variable to the value of ''dummy'' (e.g. ''EXPORT SDL_VIDEODRIVER=dummy'') before executing the program

 +===== 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 getting ''ERROR 24 (Too many open files)'' failures when Synchronet tries to open files and how do I resolve that? 
 + 
 +**Answer:**\\ 
 +You need to increase your maximum open file count. Run ''ulimit -n'' as the user you run Synchronet as to display the current open file limit. 
 + 
 +On Linux, edit ''/etc/security/limits.conf'' to edit the default limit for all users: 
 + 
 +<file limits.conf> 
 +*               soft    nofile          999999 
 +</file>
