Re: CAS-client thread issues in areaDetector IOC

Hi Mark

Is this error consistent or intermittent?

I observe it every time I start an IOC, but not immediately after startup, it shows up after some time with normal operation (acquire start/stop, enable/disable plugins etc.)

I can't seem to nail down a specific series of steps that leads to the error, but it seems consistent. I also re cloned and rebuilt everything again from scratch in a different location

to make sure something wasn't messed up in that specific set of sources, and I saw the same issue.

Regards,

Jakub

We have some tests which intentionally provoke error to ensure that
they can be handled correctly.  Unless you see any "fail" instead of "ok",
then the tests are passing and we'll have to look elsewhere.
