Hi, 

I have a little problem on the ioc I try to build, which works perfectly during hours and goes to the failure at the end...
This problem is reproductible.
In this ioc I just get/put some values from/to a SIEMENS PLC by means of the S7Nodave module.

ioc built with base 3.15.3
asyn 4.29
s7nodave 2.0.1

on Scientific Linux 7.2
Packages installed
boost-1.53.0-25.el7.x86_64
boost-devel-1.53.0-25.el7.x86_64

I get this kind of error messages (after few hours of ioc running start):

epics> 2016/09/21 16:45:54.137 PLCMyrrhaVac error while writing 2 bytes to PLC address DB7.DBB2, disconnecting...

Here the ioc is aborted. 

I read the  /usr/include/boost/optional/optional.hpp file but it doesn't mean anything for me.

Thank you in advance for help.
