Bug #10341
Updated by François ARMAND about 7 years ago
Someone tried to run datasource plugin tests and they failed with errors like:
<pre>
282/datasource/delay/node930 ; Error when getting data from datasource 'test-my-datasource' for node node59.localhost (node59): Error when fetching data from http://localhost:8282/datasource/delay/node59 ; Connection reset by peer

It very much looks like:
http://stackoverflow.com/questions/22724334/connection-reset-by-peer-and-too-many-open-files-exceptions-wile-trying-to-s
So it may be OSX specific, and trying that may help:
<pre>
sudo sysctl -w kern.maxfiles=1000200
sudo sysctl -w kern.maxfilesperproc=1000100
sudo ulimit -n 1000000
</pre>
And add:
<pre>
limit maxfiles 1000100 2000200
</pre> </pre
to /etc/launchd.conf and
And add:
<pre>
kern.maxfiles=2000400
kern.maxfilesperproc=1000200
</pre>
to /etc/sysctl.conf and restarting the computer,
And launch tests with the following command:
<pre>
$ MAVEN_OPTS="-XX:-MaxFDLimit" mvn test
</pre>
