Betreff: Clustermode: slaves recieving socket errors

Hi all,
at first I want to thank you for the help you gave me last time.
Therefore i hope you can help me another time.

The setup:
Clustermode, 1 Master, 3 Slaves. The connection between the Master and the Slaves does only rely on the Clustermode, i.e. there is no self-coded connection between them and no code relating connections at all. The interaction is based on events and each slave is interpreting the events hisself (reading values from the SG, doing some calculations, changing values on the SG).
This works fine and is also in sync.

The problem:
While using the setup, the Slaves sometimes get a Socket-error and close their application. This happens independent for each Slave and also independent of the time or number of events. The master does not crash in this way at any time.
The errormessage is printed after the Slave has finished his interpretation of the event (he is not doing his fancy stuff anymore).
The only way to reproduce it is to interact and wait until the problem occurs. Sometimes it happens fast, sometimes it takes a longer period of time.

The error message:

[EFAULT] The socket structure  address  is  outside  the  user's  addressspace.
VistaTCPSocket[690df0]::CloseSocket(0)

I have already tried removing all the dynamic generated Variables and replacing them with private members of the class they are in. (avoid memory leaks or something like this)
-> did not have any result





Have you any suggestions to solve this problem?

Thanks for your help.

Best regards
