Anyone know what be causing what appears to be something in cron (4 am or so) freezing the machine - started happening the last week or so after some bout of updates - including kde 3.5.8. After kde update I had to diable knetwork manager which made the machine interminably slow for user to login - removing it fixed that problem - nm is not runnning. Now it is freezing around 4 am .. any ideas what may be causing this ? Its been a happy F7 machine for a long time prior to this ? I could not find any interesting info in log files. Box is not visible to internet either. Thanks for any pointers ... gene
