Looks like tuned is leaking a file descriptor to its log file, or it is passing this as stdout?
If it is passing it as stdout can you open it for append rather then write. Eric, is there anyway to know which file descriptor is being used? If we could determine STDIN or STDERR we could assume it is intentional versus a different FD, is a leak.
There is no way today, but we could include that in the AVC...
I am not able to reproduce this particular AVC, but I confirm that the FD is leaking. I will provide the fix soon.
