My web server is crashing every few days unless I disable SMP with "nosmp" parameter in Grub config. It is not an hardware failure because the problem persists after moving everything to a new machine. Does anyone know which application could make the SMP system freeze with no output in syslog ?
The only kernel related stuff I can see in syslog is this :
