Hi, I encountered this exception with my RSS feed dataloader plugin. I supposed
feed_plugin should be in the
_global folder, but it is going to
squirro-0 instead. I created this data source using the RSS feed dataloader plugin on the frontend.
The problem often shows up when we have long running SQL queries in our
topicproxy service. We have since identified the issue and fixed it. This fix will be released in the Squirro release 3.5.3.
In the meantime, you can increase the
pool_size parameter from the default setting of 50 to 100, under the
topicproxy section in
/etc/squirro/topicproxy.ini file and restart the topicproxy service using
systemctl restart sqtopicproxyd.
I hope that helps.
