<p>It doesn't hang. The backtrace shows that it is waiting on the socket for new rpc commands.</p>
<p>The kamcmd error suggests that the module doesn't have enough space in its response buffer to write all the records -- see the buffer related params in the ctl readme, likely you need to increase their values.</p>
<p>As alternative, you can use jsonrpcs module with kamctl and do:</p>
<pre><code>kamctl rpc cr.reload_routes
kamctl rpc cr.dump_routes
</code></pre>
<p>jsonrpcs should not use a static internal buffer and should work out of the box.</p>
