If I understood this issue correctly, the memory not being freed is due the marshaller memory pool [0] (but I could be wrong, I didn't dive into it yet) [0] https://bugs.freedesktop.org/show_bug.cgi?id=92354 With v2 our v3 patches this should not happen anymore.. but it might be necessary some warnings in the marshaller at least. After addressing the main issue, I'll take a closer look to check if this still happens. cheers, Victor Toso _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
