Also happens every reboot server.

Any solution?

at very beginning of this error your 2006 Mysql server has gone away error indication of time out. you can set
max_allowed_packet to higher value such as 100M in your mysql configuration and see if this will sort the problem .

The solution is simple "just upgrade our server with bigger ram", supposed to be "2 GB or higher".

I guess two reasons:
- Your app has problem, try to check it
- your server's spec is too low (under 1 GB RAM, not recommended)

If you are unable to upgrade your server, maybe try to extend swap memory

Note: I have tested, only work on KVM, does not work on openVZ
