Connections errors to server (no replies)

Hi everybody,
i had tried to find existing topic about my problems but i haven't found.
So my architecture is:

- Raspberry like computer, ARM
- OS linux Raspian
- C++ the coding
- Mysql library mysql Ver 14.14 Distrib 5.5.31, for debian-linux-gnu (armv7l) using readline 6.2

i had add mysql connection in my software, it's work good for a limited time but late i have errors like:
- 2006 HY000 MySQL server has gone away
-2013 HY000 Lost connection to MySQL server at 'reading authorization packet', system error:
-2003 HY000 Can't connect to MySQL server on
-2013 HY000 Lost connection to MySQL server during query

Server is remote, it's on internet platform, and i'm sure that the internet connection is good.
After these errors the simple connection become difficulty, indeed if i restart my application all work good again until come back the errors.


It's strange and for now i haven't found solutions.

Somebody know about this behavior?

Thanks advance.
