<div class="">Thank you very much for your reply.</div>
<div class="">My NDNSIM code is version 2.6, and my program works fine until this code is modified. This error occurs only after this code is modified.</div>
<div class="">If it wasn't due to this change, what caused the error?</div>
<div class="">Maybe the code I modified earlier conflicts with this code?</div>

<pre class="">Hi,
I tried to reduce the frequency of forwarding interest packets by half. I only modified the code in forwarder.cpp in NS3, and an error occurred later.
Does anyone know how to solve this problem</pre>
<pre class="">The modified code is as follows（in forwarder.cpp）：</pre>
<pre class=""><b class=""><i class="">void Forwarder::onOutgoingInterest(const shared_ptr<pit::Entry>& pitEntry,
Face& outFace, const Interest& interest) {
NFD_LOG_DEBUG(
"onOutgoingInterest face=" << outFace.getId() << " interest=" << pitEntry->getName());
pitEntry->insertOrUpdateOutRecord(outFace, interest);
//begin
std::default_random_engine e;
std::bernoulli_distribution u;
if (interest.getName().toUri().find(std::string("manifest")) == std::string::npos && u(e)) return;
//end modify by tian 2020/10/24
outFace.sendInterest(interest);
++m_counters.nOutInterests;
}</i></b></pre>
<pre class="">The error message is as follows：</pre>
<pre class=""><i class=""><b class="">terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<nfd::rib::RibManager::Error> >'
what(): Error in setting interest filter (/localhost/nfd): request timed out</b></i>

<pre class="">Thank you very much for your help.
