The issue only shows when particles are enabled and an aircraft is actually using them - which already reduces the number of users ;-). I actually had it disabled for a long time. After enabling it recently, I also started having memory issues - on shutdown though. So that patch comes handy. The particular code has been there since the beginning of the module. Another, similar issue was fixed a while ago (http://www.gitorious.org/fg/simgear/commit/29aad066f0e57a04649b92083c4be7c6d490de31) but the property reference issue was overlooked. My guess is that there's usually no problem since the referenced property would still be part of the main property tree (?) - and have a reference there. Only when the property is dropped from the tree, should an issue occur (which would well explain my shutdown issues - but not necessarily the startup issues...). cheers, Thorsten ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.
