I see a huge memory consumption when trying to start from EGLL ( or EDDF, or EHAM, or LFPO ) with the scenery available via TerraSync/SVN. The process memory climbs to its maximum ( 2Gb for a 32 bits system - WinXP ) and the fgfs.exe process dies. This phenomenon doesn't occur at KSFO. The problem was not there yesterday morning. -Fred -- Frédéric Bouvier http://my.fotolia.com/frfoto/ Photo gallery http://fgsd.sourceforge.net/ FlightGear Scenery Designer ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
