In Response To: RPC errors (Dc Dirk Moolman)

IB that if you look at the server at the time that the users are getting RPC
and connection errors you may find that there are many more sessions than
there are users currently active. Windows apps are particularly poorly
behaved about correctly shutting down IP connections and many UNIXes, TRU64
among them IIRC, do not timeout such defunct connections. That will mean
that eventually the TRU64 server will run out of connection resources. You
can try implementing keep-alive in the Informix connections and in the TRU64
network device drivers themselves. Also try to discipline your PC users to
exit their applications via the menus rather than using the big red 'X' or
by simply logging out or shutting down. Unfortunately even when Windows
"programmers" (quotes intentional) remember to properly shutdown IP
connections on a 'normal' exit they rarely remember to link that shutdown
code into the forced quit callback code.

Similarly, going home for the night with the apps still running may,
depending on your PC policies, result in the users being force logged out
over night which is just as bad.
