rewrite process starts consuming 100% of CPU and then it's killed. Symptoms: high load of the box, rewrite core files.


Portal Access is temporarily unavailable. Core file for 'rewrite' process is generated.


This happens in a very rare situation when flash files were produced with specification violations. Specifically, list of objects within tag DefineSprite is not terminated with tag End while it always should be terminated this way.



Fix Information
