I'm probably old fashioned, but to me all that stuff is way overkill. I also tend to think that synchronizing scripts is a job for the shell, not PHP. lockfile=/var/lock/<xxxx>/file # clear out a lock older than 60mins find $lockfile -cmin +60 | xargs rm test ! -f $lockfile && ( touch $lockfile <run some php> rm -f $lockfile ) /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
