I think I know what the possible problem might be.. let me try to remember it correctly and explain... When mod_fastcgi starts up, it needs to create certain directories to deposit socket and lock files into. For the dynamic fastcgi applications, this directory is called "dynamic" and is a subdirectory of the FastCgiIpcDir. At startup, mod_fastcgi must use the *absolute* pathname of the directory because there is later a call to chdir() function (if i remember correctly) so relative pathnames make absolutely no sense. Note that we need to create some defaults at this time, so that even if FastCgiIpcDir directive is not specified, we still get a working module. In fact, if you trace the module, you will see that the function that creates dynamic directory is invoked twice. That should help you understand why absolute pathnames must be used. Now, to explain what i think is happenning when you run fastcgi... If you start up as root, in ModFastCgiInit() function, the directory will be created as root. Later on, when Apache does a setuid() and web server becomes www, any accesses of web server (i.e. mod_fastcgi) to directories will not be permitted.. i.e you will get Permission Denied error message. Same applies for the socket files and lock files, which will result in the death of the fastcgi apps. That also explains why certain stuff like directories In any case this is what i think might be happenning.. Also, on linux the socket files are ususally created with no permissions, so you either need to set umask or modify the code (although i thought it was fixed). Finally, you might create directories yourselves with permissions 755 and then see what's going on. Hope that was of some help. Stanley.
