Hello, Could you please share the full log? This must shed some light on events happened prior to the issue.
I suspect that there is some checkpoint process failure logged, you might look up for occurences of "Failed to process checkpoint" or "Failed to find checkpoint record at the given WAL pointer" in logs. Another possibility that comes to mind is WAL reservation for rebalance. Could you shortly describe the workload under which you do experience this issue? Any baseline changes, actions on WAL, what are the data volumes that are streamed/inserted/removed into caches using specific API. Specific OS/Java versions would be great as well.
