Using a big > payload (64MB in my case), a default heap and default number of handlers, > it's not too long that all the MonitoredRPCHandlerImpl hold on a 64MB > reference and once a compaction kicks in it kills everything. > The issue is that even after the RPC call is done, the packet still lives in > MonitoredRPCHandlerImpl. > Will attach a screen shot of jprofiler's analysis in a moment. > This is a blocker for 0.92.0, anyone using a high number of handlers and > bigish values will kill themselves. -- This message is automatically generated by JIRA.
