[Netarchivesuite-users] Error creating singleton of class 'dk.netarkivet.harvester.harvesting.JMXHeritrixController':

[Søren Vejrup Carlsen]

Hi Sara.
The Scheduler (currently embedded in the GUIApplication) is not responsible for launching any new jobs.
It is only responsible for submitting new jobs to the harvester-queues.
The HarvesterControllerApplication's are responsible for starting up the Heritrix instances.

Hi Jonas,

Thank you for your quick answer. 
Port 8070 is used by Heritrix. And it was used because we had 38 running 
jobs.
Is it possible that the GUIApplication would have tried to launch new jobs 
even if all our crawlers were all occupied?

Sara

Hi Sara

The cause of the error can be found in this line:
Caused by: dk.netarkivet.common.exceptions.IOFailure: Port 8070 already in 
use, or port is out of range

It means that another application on the same machine is using the port 
8070, and the application you are looking at can therefore not use the 
same port as the other application.
You can solve this problem by assigning an unused port to the application 
instead of 8070.

I cannot see exactly which port setting it is taking about, but it can 
only be one of the following:
settings.common.jmx.port
settings.common.jmx.rmiPort
settings.harvester.harvesting.heritrix.guiPort
settings.harvester.harvesting.heritrix.jmxPort

You can find them in the settings file for the application, or perhaps the 
deploy configuration file.
All of these port have to be unique and unused by other applications. 


Best regards,
Jonas

Hello Everyone,

We are still running a large test crawl at BnF.
Everything went well last week, and just coming back from weekend, I have
361 jobs that failed due to this reason : 
Error creating singleton of class
'dk.netarkivet.harvester.harvesting.JMXHeritrixController':

Do you know what could have caused this error ?

Thanks in advance!

Sara
