Hi,I am using ES 5.5 with the hot-cold architecture, by marking indices cold, he transfer indices to the cold nodes from hot nodes automatically.
the cold nodes using 30GB jvm memory setting, still having the the following log .

and now the ES crash:
No Monitoring Data Found
No Monitoring data is available for the selected time period. This could be because no data is being sent to the cluster or data was not received during that time.
Try adjusting the time filter controls to a time range where the Monitoring data is expected.
Questions:
1.using 30GB jvm memory is the right opition?
2.the recovery speed too fast?
