Dear all, I have configured my Apache HTTP Server's MPM maximum thread with the following configuration: <IfModule mpm_winnt_module> ThreadsPerChild 3465 MaxRequestsPerChild 0 ThreadLimit 4000 </IfModule> Whenever I configured the 'ThreadsPerChild' with a value more than 3463, I will hit '(OS 8)Unrecognized Win32 error code 8: Child 3316: _beginthreadex failed. Unable to create all worker threads. Created 3463 of the 3500 threads requested with the ThreadsPerChild configuration directive.'. My apache http server is running in Windows Server 2008 R2 64 bit. Would like to check, is that the maximum thread creatable? If it is not, what could be the possible reasons causing the error?
