With a large number of targets tgtadm --mode target --op show returns inconsistent results. Some targets are not listed during one run, but are shown by a run immediately after.
I grabbed the binary from the wily package and I am getting consistent results, so somewhere between 1.0.43 and 1.0.57 upstream seems to have patched the bug.
Can we get 1.0.57 (or whatever version has the fix) backported to trusty?

I grabbed the binary from the wily package and I am getting consistent results, so somewhere between 1.0.43 and 1.0.57 upstream seems to have patched the bug.
