<body dir="ltr"><div><div style="font-family: Calibri,sans-serif; font-size: 11pt;">Hi Yudi<br><br>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.<br><br>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.<br><br>Yours, Junxiao</div></div><div dir="ltr"><hr><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">From: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:yudiandreanp@live.com">Yudi Andrean</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Sent: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">4/25/2016 3:13</span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">To: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:nfd-dev@lists.cs.ucla.edu">nfd-dev@lists.cs.ucla.edu</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Subject: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">[Nfd-dev] Installing NFD 0.4.1 strangely increase CPU workload</span><br><br></div>

<p>Hi all,</p>
<p><br>
</p>
<p>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:</p>
<p><br>
</p>
<p><img tabindex="0" id="img566832" style="max-width: 99.9%; -webkit-user-select: none;" src="cid:52345627-3ccf-431e-bd51-c5dcde18fc24" crossorigin="anonymous" size="206675" contenttype="image/png"><br>
</p>
<p><br>
</p>
<p>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.</p>
<p>I uninstalled nfd, reinstalled it again, but it still used so much CPU. My NFD was not acting like this before</p>
<p><br>
</p>
<p>Any help on this suspected bug?</p>
