Another potential source of these “Java heap space” OOMs arises with the use offinalizers. If a class has afinalizemethod, then objects of that type do not have their space reclaimed at garbage collection time. Instead, after garbage collection, the objects are queued for finalization, which...
You can also increase the maximum memory size but you should keep in mind that heap memory size is a portion of the total memory in a container. As I mentioned above, it needs more spaces for metadata, thread, code cache, etc. Therefore, you have to take caution when ad...
If using OpenJDK or Sun JDK 1.6 or later, usingjstackis an option. This is useful when redirecting standard out to a file is problematic for some reason (e.g. it is not desirable to restart the JVM just to redirect standard out). Execute the following, passing in the Java process ID:...

Is there any way to get the result set metadata without execution like issue #235 ? I check codes main branch, seems like the reference file change ClickHousePreparedStatementImpl.java with PR #288 has been deprecated Contributor zhicwu commented Aug 28, 2023 Hi @suhli, could you share the...
As Wesley said before, this can happens due resource or objects being released. I just would like to add that this problem can happens due the fact that you are trying to release a ressource that has being already released.Best Regards, Rogerio...

To resolve this issue, we have a few options: Remove Existing Collection:If you no longer need the existing collection with the same name, you can remove it from the Solr cluster. You can use the Solr Admin UI or the Solr API to delete the existing collection. After removing ...
So some common reason for running out of heap memory include: 1. High volume dataflow with lots of FlowFiles active any any given time across your dataflow. (Increase configured nifi heap size in bootstrap.conf to resolve) 2. Creating a large number of Attributes on every FlowFile....
Wait... how does this tie back to unused code? There's so much of it! And not all of it's bad. Plus Shopify's 2.0 themes have removed the bulk of it becoming an issue — hallelujah! There's a long way to go, though. I spent 3 boooooring days last month playing find the GI...
