The localization for the memory limit already includes: "Freenet will need more memory if you have more queued requests, or use chat forums and other plugins, and to a lesser extent if you have a larger datastore or a fast connection." > I can file a bug if nobody wants to deal with it, just tell me :) I've filed #6506 with thoughts on how to make automatic adjustments.

ACK. As a quick fix, I would like to suggest we add the 1/3000th information to the l10n string at least. Can someone do the l10n fix for now, or at least file a bug? I can file a bug if nobody wants to deal with it, just tell me :) Thanks signature.asc Description: This is a digitally signed message part. ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

I'm not sure it is related to the Java version at hand. What I suspect to have been the culprit in your situation, is the architecture of the Java installation you employed on your Windows machine. 32-bit applications on Windows can only use 2 GiB of virtual memory (or 3 GiB with the large address awareness flag set in the executable image), and Java is quite liberal in its virtual memory usage… Oracle recommends using a 32-bit Java under most conditions, even on a 64-bit Windows installation. On 64-bit Linux, you'll probably have had a 64-bit Java by default, on Windows, it might have been a 32-bit one. If you can reproduce this on a 64-bit JVM (you can check the version and architecture with the command `java -version'), please file a bug report. -- Bert signature.asc Description: OpenPGP digital signature ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

Re: [freenet-support] data store > 500GB?
Hi Bert and Steve, Excellent and informative answers. I’ll increase max memory, physical RAM, and poke around other settings.

I think this correctly identifies the problem at hand: IIRC, bloom filters contribute to a memory usage of 1/3000th of the data store size, which would be around 1 GB of RAM for a 3TB data store — not counting memory consumption of other parts of Freenet, Java memory management overhead, etc. Your problem can probably be solved by raising the memory limit.* Apart from the limits imposed by your storage and RAM capacities, there is no limit to datastore size (apart from some 2^63 bytes limits imposed by internal representation, but that should never be an issue in the foreseeable future). Keep in mind that other settings may need additional tweaking for optimal performance when such a large datastore is used. Thank you for running Freenet! -- Bert * You can change the memory limit through the web interface as Steve pointed out, or change the `wrapper.java.maxmemory' option in wrapper.conf (after stopping Freenet): the value is the memory limit in megabytes. signature.asc Description: OpenPGP digital signature ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe
