It stops and it doesn't want to start again and says this:
parity -l sync=trace

Your database is corrupted. The easiest way is to resync. Just run

parity db kill
parity

And you should be back to normal within a few minutes. By the way, you might want to upgrade to 1.6.8 soon.

[panicape]

i usually do that but sometimes i do resync and it do it again...
Now it is working ok but is it any way to avoid this corruption? anyway...
Also, how can i upgrade it to 1.6.8?

[5chdn]

How did you install it? Usually the same procedure. If you are on linux, try

bash <(curl https://get.parity.io -Lk)

[panicape]

i downloaded the .deb installer and execute it.
i just have to execute it again or i have to unistall de previous one??

[5chdn]

Just execute it again, yes.
