Issue with PCMASS.SM in AC450

Hi everyone,

We have one issue in one AC450 controller or may be the issue is in the engineering station or in RTA. When we want to connect with the AC450 with On Line Builder in Engineering Station (Advabuild for Windows) we get the WRONG USER DISK message and we respond option 3 (Retrieve Application Segments form target) the connection crashes, when it happens we can't connect again with the controller, we have to delete the PCMASS.SM file for try a new connection. When we connect to controller by Advant Station we don't have problems. When the problem happens we have observed that PCMASS.SM file grows up to 1200KB and then connection crashed. We have APB 4.0/0, FCB 6.0/0 and ONB 3.0-0 versions.

Thanks in advanced.
