Hello, haven’t posted here before so here it goes. (Recently completed some training and was encouraged to reach out more) I figure I will start with some of the more softball questions as we are seeing various issues here: 1.
Has anyone seen issues with multiple threads using the generalTime subsystem?
a.
We are having some performance issues with a large number of clients (>100) and am trying to narrow down which futex we are spending lots of time in. I will run some tests later this week to see if the ‘timeListLock’ could be impacting
them. 2.
I am noticing that in some of our ‘casr’ outputs, we are seeing multiple TCP connections with the same PV channel connected. Is this normal behavior?
a.
For some reason, I assumed Channel Access wouldn’t allow this. If it is normal behavior, any suggestions on ways to prevent it? (I know having the users checking would be a good way
J) Hope to be participating more. Thanks, William ‘Casey’ Layne Stage Controller – Software Engineer Email: [email protected] Any opinions expressed herein are my own. They are not necessarily those of Boeing, or any other company or organization with which I am affiliated. |
