Question: I am getting the error 'Data Size To Big' on my I/O Server. The error Citect is finding does not seem to cause a problem, however the error message itself seems to cause problems. Is there some way to disable the error message? 

The error is a critical error as it normally indicates a protocol driver bug or a possible fatal problem with the user configuration. That is why it generates the software error message Dialog. These error messages can be disabled with the option [debug] SysErrDsp=0, however we don't recommend it as it will hide possible real problems. Only use this switch as a temporary measure to stop minor unwanted error messages.

You may want to use this parameter to disable the software error messages for unattended servers. If your server is locked up in a cabinet you may want to disable software errors. This way Citect will not wait until the error is acknowledged before shutting down and switching to the redundant server.
