| Subject: | IOC Startup - init value used sometimes instead of put |

Strange problem.
A. I create a bunch of PV's with initial values.
B. A little later in the code another configuration file is read for values and put is called.
C. IOC is started.
D. Some of the PV's get the correct values. Some still show init value.
If I call the configure routine to set the PV's "some time" later, the load reliability.
Thoughts?

I can add a 30 second delay, but I've lost confidence that I can guarantee initialization under circumstances where processor load might change. It looks like the "init" value is being set some random time after the PV is created. Possibly even overwriting later calls to put.
I'm using Python Soft IOC.
Thoughts?
