Hi, did you try to understand why such dump logs were generated ? Was there generated frequently ? During a specific period of the day/week/month ?
Do you have the same version deployed on every workstation ? If so : what version (maybe a known issue fixed in later builds) ?
For the deletion of the logs : dis you deploy the package through tools such as Altiris, SCCM, ... ? Because you should include in the package installation process the deletion of such files (and just before : generat a report in order to understand if this issue is at large or for specific computers).
