How to deal with memory leaks in RMagick in Ruby?

Question

Im developing web-application with Merb and im looking for some safe and stable image processing library. I used to work with Imagick in php, then moved to ruby and start us

Answer 1

Now you can tell ImageMagick which memory space should be used. I think RMAGICK_ENABLE_MANAGED_MEMORY = true and GC.start is what you need.

MANAGED_MEMORY

If true, RMagick is using Ruby managed memory for all allocations. If false, 
RMagick allocates memory for objects directly from the operating system. You can 
enable RMagick to use Ruby managed memory (when built with ImageMagick 6.4.0-11 
and later) by setting
RMAGICK_ENABLE_MANAGED_MEMORY = true
before requiring RMagick.

However, image.destroy! itself is enough to stabilize the memory consumption.
