Hi:
After updating a soft IOC with sequencer to R3.14.8.2,
I ran into some strange problem with arrays.
Originally, all was on R3.14.7 and seq-2.0.10.
About 50 vxWorks IOCs serve data into one soft-IOC with a sequence
that does something like this:
double x[80];
assign x to { "PV1", "PV2", ... };
monitor x;
....
.... when (delay(..))
     {
        .. compute something from the data in x[];
     }
After updating the soft IOC to 3.14.8.2,
with the IOCs still at R3.14.7, and the sequencer also still 2.0.10,
I no longer got all the monitors into the elements of x[].
There was no error message,
'seqShow' would still list all channels as connected,
but the data in x[] was somewhat static.
Sometimes it's all static, sometimes some elements update,
and sometimes they all update.
After changing the code to this:
...
/* No monitor x; */
.... when (delay(..))
     {
        for (...)   pvGet(x[i]);
        .. compute something from the data in x[];
     }
it worked again.
Did anybody see something similar?
Thanks,
-Kay
