<p>Dear NFD developers, </p>

<p><br>

</p>

<p>I’ve been using an old version of NFD (<i>#6028619f71e7d0eed2334d0478ff9df92cee7f18</i> ) without problem until recently. Now it fails to start and gives the following error: 

</p>

<pre>1505170300.334936 INFO: [AutoPrefixPropagator] Load auto_prefix_propagate section in rib section

Error Domain=Internal CSSM error Code=-2147416063 "Internal error #80010801 at __SignTransform_block_invoke.17 /Library/Caches/com.apple.xbs/Sources/Security/Security-57740.60.18/OSX/libsecurity_transform/lib/SecSignVerifyTransform.c:276" UserInfo={NSDescription=Internal error #80010801 at __SignTransform_block_invoke.17 /Library/Caches/com.apple.xbs/Sources/Security/Security-57740.60.18/OSX/libsecurity_transform/lib/SecSignVerifyTransform.c:276, Originating Transform=CoreFoundationObject}

<p>There is <a href="http://www.lists.cs.ucla.edu/pipermail/nfd-dev/2015-September/001330.html">

a similar post in 2015</a> which indicates the error is caused by the keychain. I tried the method mentioned in the post (unlocking the keychain mannually using commands), but still get the same error.

</p>

<p>Would you please help me figure out what's going wrong?</p>

Thanks a lot.
