Hi, At the begging I would like to thank you for that superb modules forks and forks::BerkeleyDB. They are very useful for me. I'm using them in productive environment. But on my development environment many users use that module, and there is a problem with privileges. forks:: BerkeleyDB saves by default in /tmp/pelrforks/ENV_SUBPATH subdirectory shared variables. ENV_SUBPATH is defined in forks::BerkeleyDB::Config.pm with: use constant ENV_SUBPATH => int(ENV_PID / 100).'/'.ENV_PID.'/bdb'; where ENV_PID => $$ When one user will use forks::BerkeleyDB with for example with $$ == 30001 then module will create /tmp/perlforks/300/30001 directory But when another user with $$ == 30002, module will try to crate /tmp/perlforks/300/30002 that will crash with unable to create 30002 subdirectory and program dies:( So workerund for this is for example use constant ENV_SUBPATH => int(ENV_PID * 100).'/'.ENV_PID.'/bdb'; Regards, Peter

Peter, Sounds likely that the user's umask is affecting the default permissions that mkdir users. Try the attached patch on a clean forks::BerkeleyDB 0.51 distribution. -Eric On Tue Sep 11 20:46:41 2007, jackowski.piotr@gmail.com wrote: Show quoted text

Issue has been addressed in forks::BerkeleyDB 0.052. Temp directories are now no longer restricted by user's default umask.
