Kasper Sørensen replied to subject 'Synonym catalog DC version 4.5.2' ------------------- Hi Mashud, Thanks for the information and testruns you've done here. I can inform you that for DC 4.0 we did a major refactoring of the dictionaries (and synonym catalogs) to make them more effective and have less frequent I/O operations ([https://github.com/datacleaner/DataCleaner/issues/182 issue #182] if you're interested in more detail). I have inspected your error and found still a few things that can be optimized. I will of course report that and see if we can get it improved soon. But even without those improvements, we should be able to make your system run in the current state. And the fact that the desktop app runs fine is also testament to that. To me it seems that your Tomcat (or what other webapp server is running) is tuned with a rather low memory ceiling. It runs out of memory while trying to hold the 74k dictionary terms in memory, while that is normally not an alarming amount (it's above normal I would say, but definitely not close to the half million which we would normally count as warning sign). So could you try and tune the available memory on the tomcat? Is it a dedicated web server only for DC monitor, or are other applications running on it? Is it running 64 bit java? Is it running Java 7 or Java 8? Has any memory settings been set to JAVA_OPTS, CATALINA_OPTS or on the command line when the process is starting? ------------------- View the topic online to reply - go to http://datacleaner.org/topic/1099/Synonym-catalog-DC-version-4.5.2 -- You received this message because you are subscribed to the Google Groups "DataCleaner-notify" group.
