Hi all, I am using Chainsaw V2 to manage log messages coming from a C++ application, currently the amount of messages that Chainsaw is receiving is very huge and so we are getting "Out of Memory" errors...
Is there any way to increase the Java Heap Space when launching Chainsaw? I have seen somewhere the default is 64Mb which is not ecnough for us... Another question, it seems that by defualt there is an option called "cyclic buffer" taht is set to 5000, what does this option means? Where can we configure it?
