Yes, the most interesting thing is that the log says

unexpected EOF on client connection or  could not send data to client:
Broken pipe

But this shouldn't be happening according to the code i sent because i do
NOT close the socket. Moreover the transaction only takes up a few seconds.

I read a person who had this problem and he fixed changing th cache size but
I wasn't successful.

Any ideas?
