[comp.windows.x] X Clients eating up CPU

drubin@prism.poly.edu (Dave Rubin) (05/22/91)

We are using AT&T 730X X-Windows terminals running XR4 clients off a
Convex C120.  The AT&T terminals operate in both standard and X-Windows
mode, with a feature to toggle back and forth.

The problem is, when the terminals are left in standard mode, the X-Windows
server is in a stop mode.  Therefore, clients cannot communicate with the
server during this time, causing a large number of messages to be queued.
Clients (such as xclock and xload) eat up a very large amount of CPU time
and memory when trying to communicate with the stopped server.  I suspect
that the clients are constantly trying to send messages to the server,
with no delay between retries.

Is there any way, such as an X Server or toolkit option, to limit the
client's activity when trying to communicate with a dormant server?  Or
is there some way to combat this problem on the 730X?

Any info would be appreciated ... please respond through E-mail.
