Issue:
We generate the full model DDL using the Encyclopaedia Construction Client. The last time that this worked was in Feb 2018 and the installation has not changed since then, apart from the application of a Windows Security Update. 
It is still possible to generate an individual DDL, but when you try the whole model, the generate fails with "MDEXI0045E Request file was not transferred". Successive model generates all fail, but at different points. We have tried with a different model and the same thing happens.
Environment:
Gen 8.5 Client Server Encyclopaedia
Cause:
1. The only file transfer during the CSE Construction Client -> CSE processing is when the CSE server sends back the final genstat.ctl file to the client.

2. The iefmd log file on CSE Server .log indicated a failure to create local genstat.ctl file which in turn results in a failure to send that file back to the client leading to the MDEXI0045E error message e.g.

Resolution:
Customer has found that a McAfee anti-virus update to the CSE Server has caused the genstat.ctl file to be scanned and that is causing the intermittent problem. After the scanning of the genstat.ctl file was disabled the problem was resolved.
