Ric,

> normally we see about 2 MB of free memory.

In our experience this is not enough to handle occassional transients
in the use of memory.  4 MB is a minimum (at least in 3.12.x, not
enough experience with 3.13).

Definitely.

> Is there a way to limit the number of CA clients?

The CA gateway comes to mind.

>How do other people handle this situation?

1) limit access to the control system to operations computers only
2) administratively
3) add lots of memory
4) use a gateway
