By taking a quick look at the module you specified, it seems that the mod seems to be outdated (Dated on 25/07/2003) and the mod Author also make a note about the JOIN param (Limitations: JOIN option is IRCd dependant.)
however, if you wish to use the module, try starting / setting your services in debug mode ( /os set debug on ) and load the module again. Then give the same JOIN command and if services quit again, take a look at the services log files located inside the logs folder and paste your log files back. Maybe we can get some information from the log file.
