--- Comment #5 from Dan Kegel dank@kegel.com 2009-12-19 21:02:22 --- Your log has scary messages like err:heap:HEAP_ValidateInUseArena Heap 0x110000: in-use arena 0x524c988 next block has PREV_FREE flag which indicates a corrupt heap and means a crash is likely. How soon do the err:heap messages start showing up?
