I use the following bit in my Capistrano scripts before I start Mongrel: ( [ -f pid_file ] && ( kill -0 `cat pid_file` >& /dev/null || rm pid_file ) ) which handles the typical cases (in which no process with a given pid is running, or a process is running with a different owner from the mongrel owner) but not the edge case where a process is running, with the same owner, but is no longer a mongrel process. You could supplement this with Linux/Solaris specific stuff to check if the process running is actually a mongrel. best, Erik Hetzner
