Until now i am not quite sure which script deletes the socket files, i guess it is "tmpwatch" which is called from cron.hourly, but disabling and restarting didn t solve the problem. In rc3.d it has the Numer S96postgres, after this script only sendmail,rhnsd,haldaemon,messagebus and local are executed, but none of them will delete tmp files. Any idea which and where the script is started who deletes tmp files ? System is a Red Hat ES 4 !
