The only way to reboot the machine safely is to use the Magic SysRq keys. For instance, I used : AltGr + SysRq + s, AltGr + SysRq + u and AltGr + SysRq + b which syncs the mounted file systems, remounts all the mounted file systems in Read Only mode and finally reboots the computer.
But I still can't prevent Apache from crashing the system even with SSL disabled.
