[Nfd-dev] Installing NFD 0.4.1 strangely increase CPU workload

Hi Yudi
I suspect some program is dynamically linked to an older ndn-cxx library that has been removed during the upgrade. When that program is setup as a system service, it would constantly crash and get restarted, causing init process to take all CPU. This problem has caused headache on my servers with unattended upgrades.
My suggestion is: (1) upgrade all NDN software from PPA at the same time (eg ndn-tools), don't mix versions (2) link your own programs statically to ndn-cxx, so unattended upgrade won't accidentally break your program.
Yours, Junxiao

Subject: [Nfd-dev] Installing NFD 0.4.1 strangely increase CPU workload
Hi all,
I tried uninstalling my old 0.4.0 ubuntu 14.0.4 then installing NFD 0.4.1 ppa package, and my CPU workload increases, here is what 'top' command yields on my Ubuntu laptop:
Strangely, the command init, python, and dbus-daemon ate CPU resource aggresively after nfd daemon started. I tried nfd-stop-ing the nfd, and the CPU workload went back to normal, before the nfd started again automatically (because of upstart? cmiiw), eating the CPU.
I uninstalled nfd, reinstalled it again, but it still used so much CPU. My NFD was not acting like this before
Any help on this suspected bug?
