Bug #10341

Updated by François ARMAND over 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>
