I have not used clustered Integration Servers but certainly have two Integration Servers logging against the same database. Though, theoritically I expect the same behavior with Integration Servers, I have not experienced the problem that you have outlined with the 6.1.5 implementations on windows/Solaris/AIX platforms. I have seen the behavior with Integration Server 6.5 even more vulnerable and I have an open case with TS right now on a particular model/monitor issue for 6.5
I have a reproduceable problem that I am working with TS to resolve.
Can you provide more specifics on your implementation including the versions and operating systems, etc?
