Hey, Xiaoqiang. I think the problem might actually be more insidious
than I originally thought. It seems that if the value for a char array
is every set to an array of null bytes this described error will be
thrown when a monitoring clients connects to the channel. Clients that
are already connected to the channel will also throw an error and not
update their values if the value is set to an array of null bytes.
I thought before that this problem was relatively innocuous, since it
would have only been a startup problem. But now I see that whenever my
pcaspy application clears the char array PV, all connected clients show
the bad behavior.
I haven't had any luck tracking down where in the pcaspy the problem may
be coming from.
jamie.
