The main SSH server Triton rebooted today at about 14.15 CET. The server got a kernel panic after I reloaded the grsec policy. I’ve probably reloaded the grsec policy hundreds of times before, so I’m guessing this bug is pretty rare. There is currently no updates to the stable kernel, so if it’s a bug in the kernel we’ll have to wait until the fix gets there. In the meantime I’ll be more careful with reloading the grsec policy 😉
Other servers like mail and web were not affected. Triton was back online at about 14.18 CET. Sorry for the inconvenience!
