elasticsearch crash after server reboot?

Question

elasticsearch

After restarting the server, elasticsearch stops writing data. The logs show an error like
[2015-10-27 13:20:24,503][DEBUG][action.bulk ] [Torso] [logstash-2015.10.27][3] failed to execute bulk item (index) index.... ....
I crash the contents of curator delete indices --all-indices, I restart the elastic, everything starts working. I give reboot to the server and again the same song.
What is the problem? how to solve the issue?

Here is such an init script.
Spent a few more reboots on the third or fourth reboot, the problem was gone. But I don't like it. I really want to figure out what's wrong
