Thanks! I am reluctant about the overclocking, but I run it with -856xmx ...
What does -856xmx do?
It is the memory available to the jvm, I quoted it wrong:
ps -ax
2040 ? SNl 61:45 /usr/bin/java -Xms128m -Xmx856m -jar start.jar STOP.PORT=7873 STOP.KEY=0815
-Xms128m is the minimum that is reserved at the start, and -Xmx856m is the maximum it can have, in megabytes. I often had crashes with a maximum smaller 450MB, but with giving it almost all the memory, it runs quite good.
Except that dl'ing the whole blockcahin is quite some venture.
how can you give it 856m? Don't you have a pi with 512MB? Or are you using swap? Or an other device?
