[ardour-dev] Memory Leak in 0.9.28?

[David Mulcahy]

Hello

Im no expert so please bear with me.  I have a small session that once opened 
continues to consume memory (from ps aux) until it (i think takes a while) 
runs out of memory and the following is found in dmesg.

I think it only happens with one session put I will test some more just to 
make sure.
