Forum OpenACS Q&A: Re: Invalid command name "::thread::create", invoked from within ns_mutex eval ns_mutex::throttle

Some more specific suggestion: check the configuration file of your OpenACS instance for "libthread". You should fine a few lines where Naviserver checks at startup whether the library is there or not and outputs a log statement.

Look for such log statement in your startup log file and you should find whether libthread is there or not.

Hope this helps
