<ul>
|
|
<li>Since yesterday there have been 10,000 REST errors and the site has been unstable again</li>
|
|
<li>I have blocked access to the API now</li>
|
|
<li>There are 3,000 IPs accessing the REST API in a 24-hour period!</li>
|
|
</ul>
|
|
|
|
<pre><code># awk '{print $1}' /var/log/nginx/rest.log | uniq | wc -l

3168

</code></pre>
|
|
|
|
<ul>
|
|
<li>The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29</li>
|
|
<li>100% of the requests coming from Ethiopia are like this and result in an HTTP 500:</li>
|
|
</ul>
|
|
|
|
<pre><code>GET /rest/handle/10568/NaN?expand=parentCommunityList,metadata HTTP/1.1
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li>For now I’ll block just the Ethiopian IP</li>
|
|
<li>The owner of that application has said that the <code>NaN</code> (not a number) is an error in his code and he’ll fix it</li>

|
|
<ul>
|
|
<li>Update nginx to 1.10.x branch on CGSpace</li>
|
|
<li>Fix a reference to <code>dc.type.output</code> in Discovery that I had missed when we migrated to <code>dc.type</code> last month (<a href="https://github.com/ilri/DSpace/pull/223">#223</a>)</li>

|
|
<ul>
|
|
<li>DSpace Test is down, <code>catalina.out</code> has lots of messages about heap space from some time yesterday (!)</li>
|
|
<li>It looks like Sisay was doing some batch imports</li>
|
|
<li>Hmm, also disk space is full</li>
|
|
<li>I decided to blow away the solr indexes, since they are 50GB and we don’t really need all the Atmire stuff there right now</li>
|
|
<li>I will re-generate the Discovery indexes after re-deploying</li>
