Hi,

We are using webmethods6.5 and we have used complex schedulars to schedule the flows. Sometimes the schedular invokes the flow twice at the same time with the difference of milliseconds.There could be possibility of servers going out of sync and each server executes independently or due to complex schedulars this behaviour is happening. Also I am able to see this kind of issue is not happening for all the flows.

  Need to understand is this because of cluster servers going out of Sync or the behaviour of complex schedulars.

Thanks.

That may be a bug for 6.5 in clustered environment.
SAG won’t fix it any more. I’d suggest to move up to newer version.
