[Netarchivesuite-devel] Multiple jobs submitted simultaneously under 5.3.1

[aponb at gmx.at]

If was running Nas Version on 5.3.1 in production and did get a huge 
number of jobs with the same Configurations submitted. This must be the 
behavior of https://sbforge.org/jira/browse/NAS-2614 which was fixed for 
Version 5.3.1 - the strange thing is, that I had not any problems in 
Version 5.3.0.

Is anyone experiencing the same issue?
As suggested I set settings.harvester.harvesting.sendReadyInterval to 
300 and I am using settings.harvester.harvesting.sendReadyDelay with 
value 300

Also the HarvestJobManagerApplication dies with OutOfMemory Exception, 
even when started with parameter -Xmx4096m

Do you have any thoughts on this?
