We at Keck are also having what appears to be CA problems.

In our case a client may lose connection to a subset of its
open channels. The connections never restore and the client
must be restarted. If one starts other clients, which connect
to the same channels, that new client has no problems whilst
the original client continues to be disfunctional. 

This problem affects various systems running on different
SUN workstations at different times. I am currently using
a network snooping tool to try understand what is occurring.

I am unsure if the problem is in CA repeater or the servers in the
realtime systems but I suspect the repeater. Of course I am fairly
ignorant of the CA repeater. The occurrence is very infrequent so 
it is hard to force the problem in order to study it.

If anyone has any experience with this problem or tools, which
may help, please give me a yell.
