Execption from managed client trying to access a web service.

[Tony Glombek]

I have a managed client running under WAS 6.1.0.17 generated using
Rational Application Developer v6

This client invokes a web service running on some other system.

Usually this works, but sometimes I get an exception from the client and
once this has happened I get the same error from other client trying to
get to web services running on the same system.

Can anyone suggest what might be going wrong or what I should do to
diagnose the problem?
