How so? your VIRT and RES numbers are saying there is no significant
growth in mythbackend at all.
Using "free memory" from free is not a good way to judge memory leaks
in a program. This memory includes the buffer caches and other stuff
used by the kernel, which is almost assuredly where the memory usage
is. As for actual memory used by mythbackend, you have shown nothing
that indicates that at all. The Linux memory management system is
complex and confusing for most users.

Of course it is. The kernel is keeping the memory for its buffers and caching.
I don't see a problem here.
